Keys on a piano6/15/2023 ![]() Smaller, entry-level digital pianos sometimes have just 41 keys. 73 keys give you a little over six and half octaves, which is enough to make most music. Now, that is not to say that smaller pianos don’t exist.įrom keyboards and MIDI controllers to digital stage pianos and synthesizers, other keyboard instruments often have a different number of keys. So, beyond these weird exceptions, all full-size pianos have 88 keys. So, while manufacturers continue to push the boundaries, the need for a piano with more keys is minimal.Īnd, pianos with more keys are longer and heavier, which can also impact their practicality. Do All Pianos Have 88 Keys?įirst off, Stuart & Sons makes a 102-key piano that costs a mere 220,000 Euros.īosendorfer sells a 92-key piano, with each extra key being colored black, so that the pianist can discern them from the regular notes on a piano. It could also be said that higher and lower notes are impractical and unnecessary for most songs. We can hear the sound they make, but it becomes difficult to discern individual notes in that range. There is no need for more keys.Īlso, the notes beyond those 88 keys are either considered to be too high or too low for the human ear. These days, pianos with 88 keys is a given, because almost all piano music is composed within those limits. That’s how we got the standard 88-key piano. for an orchestra, consisting of a mix of stringed instruments, woodwind instruments and more), it’s important to have this range.Ī seven-octave piano would technically be one featuring 84 notes (12 x 7 = 84), but through experimentation, a few extra keys were added and found to be practical. With composers often writing for a mix of instruments (e.g. This gives you the ability to play lower pitched notes as you move down the piano. So, you can play higher pitched notes as you move up the piano.Īs you move lower on the piano (to the left), the octaves progressively get lower. So, every distinct group of 12 notes is an octave all its own.Īs you move higher on the piano (to the right), the octaves get higher and higher. Now, to get back to the 12 notes we were originally talking about, they also represent what we commonly refer to as an “octave”. ![]() ![]() So, to be able to play every scale in every key (something every pianist should learn to do), you need to be able to play scales with black keys in addition to white keys.Īs you can imagine, some scales use black keys almost exclusively. The key of F, similarly, includes one flat, namely Bb. The key of G, for example, includes an F#. Outside of the key of C, every other key signature contains at least one sharp or flat. These are known as sharps and flats and sometimes “accidental notes”. The C major scale, therefore, is made up entirely of natural notes, and that’s part of what makes it easy to play, even for a beginner. The white keys therefore represent “natural notes” – A, B, C, D, E, F and G – which are whole-step intervals.īeginner pianists typically begin by learning to play in the key of C, which includes the notes C, D, E, F, G, A and B. What’s The Difference Between White Keys & Black Keys?Īccording to music theory, there are 12 notes in music (the 12-tone Western scale).Ī, A#/Bb, B, C, C#/Db, D, D#/Eb, E, F, F#/Gb, G, G#/Ab Every octave has five black keys, with at least one white key in between each one. How Many Black Keys Are There On A Piano?Īssuming 88 keys, there will be 36 black keys on a piano. There are seven white keys within every octave of the piano – think of the C Major scale, with seven white keys in a row before repeating itself in different octave ranges. How Many White Keys Are There On A Piano? This became the world-standard, and today most modern, full-size pianos have 88 keys. In the late 1880s, the seven-octave 88-key piano was created by Steinway. Piano makers continued to try out a variety of configurations. But their compositions took them beyond the five-octave range offered on most instruments.īecause composers wanted to make more expressive music, they collaborated with piano makers and manufacturers started experimenting with different ranges. The demand for pianos started to rise as composers starting writing music for the piano. Similarly, the first piano only had 49 keys and many models that followed came with 60 keys, just like the harpsichord. The harpsichord had only 60 keys, which means that everything that was written for keyboard instruments was limited to the harpsichord’s five-octave range.
