It&#8217;s unique in that it can provide stunningly rich and complex harmonies as well as catchy, fluid or staccato melodies &#8211; from classical and jazz to rock and pop.

If you&#8217;re interested in the technology behind these instruments and are asking the question, &#8220;<strong>How does a piano work?<\/strong>&#8220;, this guide will explain all, from strings to the soundboard and how acoustic and digital pianos differ.<\/span><\/span><\/p>\n<p>[\/et_pb_text][et_pb_text admin_label=&#8221;How does a piano work?&#8221; _builder_version=&#8221;4.17.4&#8243; background_size=&#8221;initial&#8221; background_position=&#8221;top_left&#8221; background_repeat=&#8221;repeat&#8221; custom_padding=&#8221;20px||||false|false&#8221; border_width_top=&#8221;2px&#8221; border_color_top=&#8221;#f08000&#8243; global_colors_info=&#8221;{}&#8221;]<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_does_a_piano_work\"><\/span><span data-contrast=\"auto\">How does a piano work?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The acoustic piano is made up of a variety of internal mechanisms, namely the strings, hammers, dampers, and soundboard. In essence, the pressing of a key triggers a hammer to hit the appropriate string, which then creates vibrations through the soundboard, causing the piano to sound.<\/p>\n<hr \/>\n<h4><span class=\"ez-toc-section\" id=\"Strings\"><\/span><span data-contrast=\"auto\">Strings<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p><span data-contrast=\"auto\">An acoustic piano&#8217;s strings are made from high-strength steel that varies in length, thickness, and material to produce different pitches. Bass notes, for instance, require longer, thicker strings, often wound with copper. While treble notes rely on shorter, thinner ones.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<hr \/>\n<h4><span class=\"ez-toc-section\" id=\"Hammers\"><\/span><span data-contrast=\"auto\">Hammers<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>The hammers are the more complex parts of a piano. Made from wood and covered in felt, they hit the string and then fall away quickly, allowing the note to sustain itself. <span data-contrast=\"auto\">The sustain is controlled by an escapement mechanism, which ensures the hammer is released from the strings immediately after striking. <\/span><\/p>\n<p><span data-contrast=\"auto\">Grand pianos use a double escapement system, allowing the keys to be pressed rapidly &#8211; essential for expressive and fast playing.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">One thing to consider with acoustic piano hammers is that the felt compacts over time, affecting tone quality. A tuning technician can adjust this by softening the felt to create a more balanced sound.\u00a0<\/span><\/p>\n<hr \/>\n<h4><span class=\"ez-toc-section\" id=\"Dampers\"><\/span><span data-contrast=\"auto\">Dampers\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p><span data-contrast=\"auto\">Dampers in an acoustic piano control sound by stopping string vibrations when a key is released. Each damper consists of a felt pad that rests on the strings and lifts only when a key is pressed. This allows the strings to vibrate freely while the note is sustained. When the key is released, the damper returns to its position, silencing the sound.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Dampers are a crucial part of the piano &#8211; without them, the instrument would produce a continuous blur of overlapping tones, producing a messy sound.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Most keys have a damper, except for the higher-pitched strings, as their vibrations naturally fade quickly. If you don&#8217;t want the strings to be dampened, the sustain pedal is there to lift all dampers and let the notes ring out. <\/span><\/p>\n<hr \/>\n<h4><span class=\"ez-toc-section\" id=\"The_soundboard\"><\/span><span data-contrast=\"auto\">The soundboard<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p><span data-contrast=\"auto\">The soundboard in an acoustic piano amplifies the vibrations of the strings and helps shape the instrument\u2019s tone. When a hammer strikes the strings, their vibrations travel through the bridge and into the soundboard, which then resonates to project the sound.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Soundboards amplify the piano\u2019s volume and warmth. They&#8217;re typically made from high-quality wood, such as spruce, and feature attached wooden ribs to help distribute vibrations evenly. Without a soundboard, the piano\u2019s strings would produce only a faint sound instead of the rich, full-bodied tone we associate with the instrument.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<hr \/>\n<h4><span class=\"ez-toc-section\" id=\"Pedals\"><\/span><span data-contrast=\"auto\">Pedals<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p><span data-contrast=\"auto\">Piano pedals provide greater control over the instrument\u2019s sound and dynamics. We&#8217;ve mentioned the sustain pedal (the rightmost pedal) &#8211; this lifts all the dampers, allowing notes to sound for longer after the keys are released.\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">The sostenuto pedal (the middle pedal) sustains only the notes that are held down when the pedal is pressed, while all others remain unaffected. This is particularly useful for sustaining bass notes while playing staccato in the treble.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">The una corda pedal (the leftmost pedal) softens the sound, though its function varies depending on the type of piano. On a grand piano, for example, the una corda pedal shifts the action so the hammers strike fewer strings, producing a gentler tone. In an upright piano, it moves the hammers closer to the strings, reducing their impact.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Some upright pianos also feature a practice pedal, which lowers a felt strip between the hammers and strings. This significantly dampens the volume, making it ideal for quiet practice sessions.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-42895 size-full\" src=\"https:\/\/storage.googleapis.com\/stateless-blog-g4m-co-uk\/2025\/01\/G4M-Sonori-Digital-Grand-Piano.jpg\" alt=\"\" width=\"1330\" height=\"665\" srcset=\"https:\/\/storage.googleapis.com\/stateless-blog-g4m-co-uk\/2025\/01\/G4M-Sonori-Digital-Grand-Piano.jpg 1330w, https:\/\/storage.googleapis.com\/stateless-blog-g4m-co-uk\/2025\/01\/G4M-Sonori-Digital-Grand-Piano-600x300.jpg 600w, https:\/\/storage.googleapis.com\/stateless-blog-g4m-co-uk\/2025\/01\/G4M-Sonori-Digital-Grand-Piano-1024x512.jpg 1024w, https:\/\/storage.googleapis.com\/stateless-blog-g4m-co-uk\/2025\/01\/G4M-Sonori-Digital-Grand-Piano-768x384.jpg 768w, https:\/\/storage.googleapis.com\/stateless-blog-g4m-co-uk\/2025\/01\/G4M-Sonori-Digital-Grand-Piano-1080x540.jpg 1080w, https:\/\/storage.googleapis.com\/stateless-blog-g4m-co-uk\/2025\/01\/G4M-Sonori-Digital-Grand-Piano-1280x640.jpg 1280w, https:\/\/storage.googleapis.com\/stateless-blog-g4m-co-uk\/2025\/01\/G4M-Sonori-Digital-Grand-Piano-980x490.jpg 980w, https:\/\/storage.googleapis.com\/stateless-blog-g4m-co-uk\/2025\/01\/G4M-Sonori-Digital-Grand-Piano-480x240.jpg 480w\" sizes=\"auto, (max-width: 1330px) 100vw, 1330px\" \/><\/p>\n<p>[\/et_pb_text][et_pb_text admin_label=&#8221;How does a digital piano work?&#8221; _builder_version=&#8221;4.17.4&#8243; background_size=&#8221;initial&#8221; background_position=&#8221;top_left&#8221; background_repeat=&#8221;repeat&#8221; custom_padding=&#8221;20px||||false|false&#8221; border_width_top=&#8221;2px&#8221; border_color_top=&#8221;#f08000&#8243; global_colors_info=&#8221;{}&#8221;]<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_does_a_digital_piano_work\"><\/span><span data-contrast=\"auto\">How does a digital piano work?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Understanding the basics of how an acoustic piano works will help you grasp the technology of a digital piano. In short, a digital piano&#8217;s job is to replicate the workings and sound of its acoustic counterparts, and it uses sensors and sampling or modelling techniques to achieve this.<\/p>\n<hr \/>\n<h4><span class=\"ez-toc-section\" id=\"Sensors\"><\/span><span data-contrast=\"auto\">Sensors<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p><span data-contrast=\"auto\">A digital piano uses sensors to detect how each key is played. Instead of hammers striking strings, the sensors measure the force and speed of your keystrokes, converting them into digital signals. These signals then trigger high-quality recorded samples or computer-generated sounds, replicating the response of an acoustic piano.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Advanced digital pianos feature multiple sensors per key to capture the small variations in touch, allowing for more control over volume and tone. Some models also include escapement simulation to mimic the feel of an acoustic piano\u2019s mechanism. Since digital pianos do not have physical strings, they rely on built-in speakers or headphones to produce sound. <\/span><\/p>\n<p><span data-contrast=\"auto\">Hybrid pianos use a natural mechanism for the playing action combined with a sensor. An example of this is the\u00a0 <\/span><a href=\"https:\/\/www.gear4music.com\/Keyboards-and-Pianos\/Casio-GP510-Grand-Hybrid-Digital-Piano-Polished-Ebony\/346H\" target=\"_blank\" rel=\"noopener\"><b><span data-contrast=\"none\">Casio GP510 Grand Hybrid Digital Piano.<\/span><\/b><\/a><span data-contrast=\"auto\"> This particular model uses the Natural Grand Hammer mechanism and Casio sensors and is the result of a collaboration between C.Bechstein and Casio.<\/span><\/p>\n<hr \/>\n<h4><span class=\"ez-toc-section\" id=\"Sampling_or_modelling\"><\/span><span data-contrast=\"auto\">Sampling or modelling<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p><span data-contrast=\"auto\">Digital pianos generate sound using either sampling or modelling. <\/span><span data-contrast=\"auto\">Sampling involves recording the sound of an acoustic piano at various dynamics and articulations. Each note is captured multiple times to ensure a realistic representation. <\/span><\/p>\n<p><span data-contrast=\"auto\">High-end digital pianos use sampling, a process that involves layering multiple recordings to replicate the differences of a real instrument. This process requires precise microphone placement and post-processing to create an authentic, expressive sound.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Modelling, on the other hand, synthesizes sound in real-time.

Made from wood and covered in felt, they hit the string and then fall away quickly, allowing the note to sustain itself. <span data-contrast=\"auto\">The sustain is controlled by an escapement mechanism, which ensures the hammer is released from the strings immediately after striking. <\/span><\/p><p><span data-contrast=\"auto\">Grand pianos use a double escapement system, allowing the keys to be pressed rapidly - essential for expressive and fast playing.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">One thing to consider with acoustic piano hammers is that the felt compacts over time, affecting tone quality. A tuning technician can adjust this by softening the felt to create a more balanced sound.\u00a0<\/span><\/p><hr \/><h4><span data-contrast=\"auto\">Dampers\u00a0<\/span><\/h4><p><span data-contrast=\"auto\">Dampers in an acoustic piano control sound by stopping string vibrations when a key is released. Each damper consists of a felt pad that rests on the strings and lifts only when a key is pressed. This allows the strings to vibrate freely while the note is sustained. When the key is released, the damper returns to its position, silencing the sound.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">Dampers are a crucial part of the piano - without them, the instrument would produce a continuous blur of overlapping tones, producing a messy sound.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">Most keys have a damper, except for the higher-pitched strings, as their vibrations naturally fade quickly. If you don't want the strings to be dampened, the sustain pedal is there to lift all dampers and let the notes ring out. <\/span><\/p><hr \/><h4><span data-contrast=\"auto\">The soundboard<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/h4><p><span data-contrast=\"auto\">The soundboard in an acoustic piano amplifies the vibrations of the strings and helps shape the instrument\u2019s tone. When a hammer strikes the strings, their vibrations travel through the bridge and into the soundboard, which then resonates to project the sound.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">Soundboards amplify the piano\u2019s volume and warmth. They're typically made from high-quality wood, such as spruce, and feature attached wooden ribs to help distribute vibrations evenly. Without a soundboard, the piano\u2019s strings would produce only a faint sound instead of the rich, full-bodied tone we associate with the instrument.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p><hr \/><h4><span data-contrast=\"auto\">Pedals<\/span><\/h4><p><span data-contrast=\"auto\">Piano pedals provide greater control over the instrument\u2019s sound and dynamics. We've mentioned the sustain pedal (the rightmost pedal) - this lifts all the dampers, allowing notes to sound for longer after the keys are released.\u00a0<\/span><\/p><p><span data-contrast=\"auto\">The sostenuto pedal (the middle pedal) sustains only the notes that are held down when the pedal is pressed, while all others remain unaffected. This is particularly useful for sustaining bass notes while playing staccato in the treble.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">The una corda pedal (the leftmost pedal) softens the sound, though its function varies depending on the type of piano. On a grand piano, for example, the una corda pedal shifts the action so the hammers strike fewer strings, producing a gentler tone. In an upright piano, it moves the hammers closer to the strings, reducing their impact.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">Some upright pianos also feature a practice pedal, which lowers a felt strip between the hammers and strings. This significantly dampens the volume, making it ideal for quiet practice sessions.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p><p><img class=\"aligncenter wp-image-42895 size-full\" src=\"https:\/\/storage.googleapis.com\/stateless-blog-g4m-co-uk\/2025\/01\/G4M-Sonori-Digital-Grand-Piano.jpg\" alt=\"\" width=\"1330\" height=\"665\" \/><\/p><hr \/><h3><span data-contrast=\"auto\">How does a digital piano work?<\/span><\/h3><p>Understanding the basics of how an acoustic piano works will help you grasp the technology of a digital piano. In short, a digital piano's job is to replicate the workings and sound of its acoustic counterparts, and it uses sensors and sampling or modelling techniques to achieve this.<\/p><hr \/><h4><span data-contrast=\"auto\">Sensors<\/span><\/h4><p><span data-contrast=\"auto\">A digital piano uses sensors to detect how each key is played. Instead of hammers striking strings, the sensors measure the force and speed of your keystrokes, converting them into digital signals. These signals then trigger high-quality recorded samples or computer-generated sounds, replicating the response of an acoustic piano.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">Advanced digital pianos feature multiple sensors per key to capture the small variations in touch, allowing for more control over volume and tone. Some models also include escapement simulation to mimic the feel of an acoustic piano\u2019s mechanism. Since digital pianos do not have physical strings, they rely on built-in speakers or headphones to produce sound. <\/span><\/p><p><span data-contrast=\"auto\">Hybrid pianos use a natural mechanism for the playing action combined with a sensor. An example of this is the\u00a0 <\/span><a href=\"https:\/\/www.gear4music.com\/Keyboards-and-Pianos\/Casio-GP510-Grand-Hybrid-Digital-Piano-Polished-Ebony\/346H\" target=\"_blank\" rel=\"noopener\"><b><span data-contrast=\"none\">Casio GP510 Grand Hybrid Digital Piano.<\/span><\/b><\/a><span data-contrast=\"auto\"> This particular model uses the Natural Grand Hammer mechanism and Casio sensors and is the result of a collaboration between C.Bechstein and Casio.<\/span><\/p><hr \/><h4><span data-contrast=\"auto\">Sampling or modelling<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/h4><p><span data-contrast=\"auto\">Digital pianos generate sound using either sampling or modelling. <\/span><span data-contrast=\"auto\">Sampling involves recording the sound of an acoustic piano at various dynamics and articulations. Each note is captured multiple times to ensure a realistic representation. <\/span><\/p><p><span data-contrast=\"auto\">High-end digital pianos use sampling, a process that involves layering multiple recordings to replicate the differences of a real instrument. This process requires precise microphone placement and post-processing to create an authentic, expressive sound.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">Modelling, on the other hand, synthesizes sound in real-time. Instead of playing back recorded samples, modelling algorithms simulate how a piano string vibrates, how the soundboard resonates, and how different playing techniques influence the tone. This allows for greater responsiveness and customisation.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">Some digital pianos combine both methods, using samples for a natural tone and modelling for how the tone behaves. This hybrid approach balances authenticity with adaptability, making digital instruments more expressive. <\/span><\/p><p><span data-contrast=\"auto\">The <\/span><a href=\"https:\/\/www.gear4music.com\/Keyboards-and-Pianos\/Kawai-CN201-Digital-Piano-Satin-Black\/4WSR\" target=\"_blank\" rel=\"noopener\"><b><span data-contrast=\"none\">Kawai CN201 digital piano<\/span><\/b><\/a>, for example,<span data-contrast=\"auto\"> samples their flagship Shigeru Kawai SK-EX and utilises Kawai's progressive harmonic imaging technology to follow the tonal changes and dynamics of your playing.<\/span><\/p><p><img class=\"aligncenter wp-image-20086 size-full\" src=\"https:\/\/storage.googleapis.com\/stateless-blog-g4m-co-uk\/2022\/11\/Kawai-CN201-Digital-Piano-Satin-Black.jpg\" alt=\"Win a Kawai CN201 Piano\" width=\"1330\" height=\"665\" \/><\/p><hr \/><h3><span data-contrast=\"auto\">Innovative digital piano technology<\/span><\/h3><p><span data-contrast=\"auto\">Kawai, Yamaha, and Casio are among the most innovative brands in the digital piano industry, pioneering technology that enhances realism, playability, and expression. <\/span><\/p><p><span data-contrast=\"auto\">If you're choosing between these brands, Kawai excels in wooden key actions and rich harmonic imaging, Yamaha leads in resonance modelling and advanced key mechanics, while Casio focuses on intelligent sound processing and hybrid key actions at an accessible price.\u00a0<\/span><\/p><hr \/><h4><span data-contrast=\"auto\">Kawai<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/h4><p><span data-contrast=\"auto\"><img class=\"wp-image-10177 size-medium alignright\" src=\"https:\/\/storage.googleapis.com\/stateless-blog-g4m-co-uk\/2022\/06\/Kawai-CN301-e1740155040936-300x300.jpg\" alt=\"\" width=\"300\" height=\"300\" \/>Kawai's Grand Feel wooden-key actions are designed to replicate the touch of a grand piano. <\/span><\/p><p><span data-contrast=\"auto\">Unlike standard plastic key actions, the brand use wooden keys with pivot points - similar to those found in acoustic pianos.

Their hammers, strings, and soundboard create organic resonance - something digital models can simulate but not fully replicate. <\/span><\/p><p><span data-contrast=\"auto\">The weighted keys and escapement mechanism offer precise control over dynamics, making acoustic pianos ideal for classical pianists, serious learners, and those who appreciate traditional craftsmanship.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">Digital pianos, on the other hand, are more practical for modern living, offering volume control, headphone connectivity, and a variety of instrument sounds. <\/span><\/p><p><span data-contrast=\"auto\">We recommend opting for a digital piano with good key weighting and an advanced sound engine, like from one of the brands above. This way, you have the best of both worlds - a close replication of the tone and resonance of an acoustic piano and the convenience of a digital piano. You also don't need to tune a digital piano or wait for it to \"settle\" when you install it in your home - another bonus!\u00a0<\/span><\/p><hr \/><h3><span data-contrast=\"auto\">FAQs<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/h3><h4><span data-contrast=\"auto\">How does a piano make a sound?\u00a0<\/span><\/h4><p><span data-contrast=\"auto\">When you press a key on a piano, the felt-covered hammers hit the string, which then sends vibrations through the soundboard, therefore causing the piano to make a sound. Different string lengths and tensions produce various pitches, while the sustain pedal allows notes to resonate longer. <\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p><hr \/><h4><span data-contrast=\"auto\">How does the piano mechanism work?\u00a0<\/span><\/h4><p><span data-contrast=\"auto\">The piano mechanism works through a complex system of keys, hammers, dampers, and strings. Pressing a key lifts a hammer, which strikes a string to create sound. The damper lifts to let the string vibrate freely, and when the key is released, the damper stops the vibration. This system enables dynamic control and expression. <\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p><hr \/><h4>How does a piano play different notes?<\/h4><p>An acoustic piano plays different notes by engaging different strings when a key is pressed.
