What is Polyphony in Digital Piano? (2023)

The Term poly refers to many and phony refers to sound and polyphony is the maximum number of notes that the keyboard can play simultaneously. It could range from 16 to 256 notes and pianists can choose instruments with their desired number of polyphonies while buying the digital pianos. 

It is important to look for the number of polyphony notes in the digital pianos, as it is one of the unique features that differentiate the digital piano from an acoustic piano and is an important component that fosters one’s musical journey. Let us discuss this unique feature in detail and how much polyphony is just right to foster the pianist in you.

What is Polyphony in Digital Piano

About Polyphony

Polyphony is the number of notes that can be played on a piano at one time. Though logic says that with ten fingers in both hands, we can play only 10 notes at a time, with the sustain pedal in the digital piano that stops the notes on the piano and elongates the sound as the key is released, we can play more than 80 separate sounds. You only have to leave the sustain pedal down and play note by note. Comparing the acoustic piano with the digital piano, the former has unlimited polyphony as its sounds are not recorded as that of the digital piano. 

Digital pianos generally have a polyphony sound of 128 or above and some even have 256 or even 48 different sounds to play at once. When we say phony or sound, it could refer to two different things, the number of individual notes that we are playing and the number of voices that we are using on the piano such as the harpsichord, strings, vibraphone, etc., depending on what the digital piano offers.

For instance, if we are playing five notes with only the piano voice and start using strings with the piano sounds, it not becomes ten notes and while concurrently using the pedal, we can add up the polyphony and have as many notes on the piano as possible. Even the tracks and other instruments that play in the background sound can add up to the polyphony. In the duet mode, for instance, where two people can play the piano at the same time, there are 20 fingers now to explore the maximum possibility of the polyphony.

Importance of Polyphony in a Digital Piano

Polyphony matters to all pianists who are playing in the different music genres and with lower-end pianos that have limited polyphonies, the sounds keep cutting off and hinders the progress of the musician beyond a certain level. Thus, having a digital piano with maximum polyphony is beneficial as it helps in playing different styles of music and will not deceive the performer on stage.

Polyphony is mandatory for mixing voices in music and can be highly beneficial for pianists sliding up their professional cadre. They are important for music performers who create music or do stage shows and for music teachers to teach different genres of music to the students. Thus it becomes mandatory to buy a piano with at least 128 polyphonies though there are pieces with 192 or 256 polyphonies at a higher cost. 

Above all, it helps music students to learn fast and makes their music learning journey all the more interesting. Many beginners find that having a metronome or a background track with drum beats helps them to learn piano lessons better and also enhances their music-playing interests.

Every digital piano player, regardless of genre, values polyphony. This is because if users buy a piano with insufficient polyphony, they will find it frustrating when they advance beyond a certain level and try to make music but the sounds keep cutting off. This is especially the case if one is playing classical music on the digital piano when you frequently have a lot of things going on in each hand at the same time.

Users cannot afford to have an inferior instrument jeopardize their performance if they are using the piano to perform, as a stage piano, or to give concerts. This is especially true when mixing voices, such as if users want a piano, as well as strings, sound for a ballad, or some such. While few keyboardists will ever perform that many notes at once, many people would like the possibility of playing complicated, multi-part layers that require far more polyphony than just a one-instrument sound would ever necessitate. Consider that how strongly a sound is blended seamlessly can have an adverse effect on polyphony on certain sound modules or keyboards. 

Polyphony Notes

Many low-cost entry-level pianos will only have 64 polyphony. 64 is a very small figure even for beginners. Even though beginners will not inevitably be trying to play complicated chords as well as runs down and up the keyboard, they may be keen on some other characteristics of the piano that require a lot of polyphony. Experimenting with the various features is a big part of the enjoyment of learning the piano. Many beginners discover that employing a metronome, a drum-backing track, or the instrumental feature can help them learn faster.  These extra features can have a significant impact on polyphony, so even beginners should avoid pianos with a polyphony of 64 unless they’re certain they’ll only be playing “Chopsticks” on a simple piano patch with really no extra drums or features. A polyphony of 128 is significantly reasonable and allows players to be more creative with their piano. This is a good starting point for the average player’s polyphony. 

Factors to Consider When Thinking About Polyphony

On digital pianos, polyphony refers to the highest amount of notes that can be played at the same time. It is feasible to have 16, 32, 64, 128, or 256 notations. It does not matter how nice the digital piano makes a sound or feels if users keep dropping notes while playing. A digital piano’s polyphony signifies the number of sounds this can play at one time. This normally varies from 64 to 256-note polyphony, as well as the sounds include a variety of notes, instruments, tracks, and other elements. Higher polyphony digital pianos enable more technical and complex use. 

If you need a digital piano that simulates an acoustic piano for basic practice, you’ll certainly respect 32-note polyphony. In the unlikely event that you start losing notes while using the manage pedal, you will be oblivious to it. If the optimum note number is reached, digital pianos utilize algorithms to decide which notes to drop. 

On occasion, they will select notations that could be decided to drop without the listener noticing. So, the bad news is that achieving maximum polyphony will result in note loss. The great news is that it is possible that one will not notice. Certainly, go ahead and document different tracks on the digital piano to get a greater note of polyphony. Every additional track added on top of an existing track contributes to the biggest polyphony. The digital piano counts the previous track as well as your current playing, all while aiming for maximum polyphony. When one starts adding different sounds and voices to different tracks, one can see how quickly one can reach an optimum polyphony of 32 in the song. Similarly, if they want to use layering effects in an incredible arrangement, get some more than 32-note polyphony. The layering effect allows for different voices/tones to be played for every stroke of the key. When a fantastic piano is used and string impact, each keypress uses one note of the total polyphony for the wonderful piano tone and one note for the chords. This, one could argue, is a portion of the total polyphony check. 

Applications of Polyphony in the Digital Piano – What Uses Up Polyphony?

There are many different aspects in the piano that makes use of polyphony, though they render their maximum contribution for playing piano notes. The sustain pedal is one of the biggest factors that influences how polyphony is been used. While playing with a sustain pedal we get multiple notes layered on top of each other until the pedal gets released.

Thus, every single note that is been played while the pedal was depressed contributes to polyphony. Also, patches in some keyboards carry a slow decay that lasts long even after the key is released. These sounds can also build upon each other requiring additional polyphony. 

Piano notes feature lasting reverbs and sympathetic string resonances and though these are not recognizable, these minor nuances also contribute towards the number of polyphonies that are been used. For doubling effects in music, while attempting to layer the piano sounds with the string sounds, we can witness the use of polyphonies. For recording new tracks and to play them as a custom backing track, we have to use a large amount of polyphony.

Aside from playing notes, there are other variables in a keyboard that contribute to polyphony. The sustain pedal has a significant impact on how often polyphony is used. Numerous notes are stacked on top of each other when using a sustain pedal till the pedal is released. That is, every note played because the pedal was depressed helped contribute to the polyphony number. Similarly, many keyboard patches have such a slow decay which lasts a long time after the key is released. These sounds also start building up on each other, which is why more polyphony is required.

Many people believe that long-decay sounds can only be found on specialised synth spots or string makes it sound with such a long reverb, but any good piano sound should include some extra decay time. Any respectable piano patch would then have the same characteristics with enduring reverbs as well as sympathetic string resonances, just like an acoustic piano’s notes ring out when the hammer hits the string. These minor nuances, while not easily discernible, contribute to the polyphony employed. Stereo patches on certain keyboards use twice as much of polyphony per note.

The said doubling of polyphony rapidly exhausts pianists and can result in unsightly note dropouts. The same effect can occur if you layer your sounds. Layering strings beneath a piano is a common example. Even if you only use one patch at a time, you could discover that so many pre-made patches use multiple layers of patches to start creating their sounds. Also, when trying to play relatively easy music with such a single patch, it is clear how rapidly polyphony can be depleted. Even more polyphony is required for your digital piano to function properly if you want to use its more advanced features.

Many pianos’ onboard metronomes generate click tracks using one to two voices of polyphony. Trying to play alongside a drum backing track uses more polyphony, as do keyboards that enable you to play together with pre-recorded accompaniment. Some digital pianos allow individuals to record a few songs and return them as a custom music track. Users can envision that doing so requires a lot of polyphony.

How Polyphony Affects Performance

A lower polyphony digital piano limits how much can be played at once, and you may get stuck attempting to combine including an external track or metronome. This results in a less intuitive practise session, which is inefficient use of the time. The limitations of lower synth sounds pianos also limit how far one can progress. Specific voices and parts may be cut off, especially in complex passages like those found in orchestral music.

When performing live, high polyphony makes it possible one to do much more, such as blending voices and introducing both these elements on the fly. Stage pianos are especially well-known for this, and more is polyphony improves your performance. Playing with low polyphony on stage is a recipe for failure. This allows notes to emerge from the sound, which the audience will notice. Trying to hit the right notes does not mean much if the digital piano’s polyphony is maxed out and does not let them through.

Bottom Line

As a pianist, if you want to play many instruments in your notes and wish to record different tracks on your digital piano, then you need a higher note polyphony. Pianos from Casio, Korg, Roland, and Yamaha are moderately priced but feature higher polyphony for budding pianists.

If you are worried about losing notes when using the support pedal, try this. On the digital piano, play the two greatest reduced A notes. Glide with both hands while holding them with support pedal. If the digital piano uses a calculation to drop off a fraction of a notes in the glissando, you should not lose the two low An’s. Users will not notice whether they are losing notes in the glissando. It is ideal if you don’t lose the low A’s, but if you do on your digital piano, it’s not the end of the world.

When looking at digital pianos, you should become familiar with the term polyphony, and you ought to be conscious of the limitations of any electric piano you sit down at. When looking for your own digital piano, make sure it matches your current level of experience as well as where users want to go. Purchasing a higher polyphony piano enables advantage of its innovative features and improve your playing abilities. This will end up making the dreams of playing the piano a lot more attainable. 


Frequently Asked Questions (FAQs)

1. What are Metronomes?

Whether you are a novice or a highly experienced pianist, using the metronome built into the digital piano is often the simplest and most accessible option. Using a metronome to keep track of your tempo is one of the fundamentals, and it is easy to overlook the fact that it consumes some of the available voices.  

2. What are Slow Decays?

Unlike monophonic keys, which can only play one note at a time, polyphonic keyboards have patches which allow for note decay. This means allowing the sound to linger and fade innately after key is cleared, resulting in a nice natural sound layering.
The misconception that this is only available in specialised synth or string makes it sound is incorrect, and it can cause issues with limited polyphony digital pianos.

3. What are Duets?

A second player increases the number of fingers on the keys and easily doubles the number of sounds that can be played at the same time. The actual consequences of a second player are determined by the nuance of their role. Even a minor feature can cause problems. 

4. Why is It Important to Know About Stereo?

On a digital piano, some of the tones/voices may be in stereo. This means that a single note may well have two different noises recorded that play in the background to simulate the sound of the an acoustic. When this happens, you’re using two notes of polyphony for every key you hit instead of one. This effectively converts a 32-note polyphony keyboard into a 16-note polyphony keyboard. This will only happen on stereo impacts, but most modern digital musical instruments do have stereo note sounds. 

5. What Happens When Polyphony Limit is Exceeded? 

As a result, when the polyphony is exceeded, it appears that string sounds are being chopped off at random, and the sound becomes thinner as new notes have been played.
