However, if you actually count the keys, you'll notice that there are actually only seven notes in an octave. The term " octave" came from the fact that it is a group eight "natural" notes (the white keys). No, there won't be any 'missing black notes'. But I think this question is about 'songs', today, played on a piano. We could talk about the lowest note on a bass guitar, or about how certain guitar 'licks' only work in certain keys due to using open strings. Or we could talk about schemes of tuning from the Baroque era that limited the possibilities of transposition. We could discuss highly technical pieces for piano that would become real finger-twisters if transposed.

Probably to put the vocalist in their optimum range, with the high notes high enough to be impressive but no so high as to be impossible! YOUR performance might be best in yet another key, and it won't have anything to do with ease of playing on the keyboard! This is all very well, but remember WHY it might have been recorded in that key. It can be surprising how often a 'pop' song is recorded in a 'hard' key like G♭ major or B major, while the sheet music is published in F or C. And yes, sometimes a piece that was originally in a 'hard' key is adapted for beginners in an 'easy' one. Yes, any piece of piano music can be transposed to any key. In other words, it's not possible for there to be a "missing black note" whatever note the transposition requires, be it black or white, it will be present. Note that F♯ G♯ A♯ is enharmonically equivalent to G♭ A♭ B♭. But there are several different possibilities for black and white keys:Īnd so on. The third note is four half steps above the first and two half steps above the second. Some notes will move from a black key to a white key, or vice versa, but the distance between any two notes, as counted in half steps (semitones), will remain the same.Ĭonsider "do re mi." The second note is two half steps above the first. Whether a key is black or white doesn't affect this. The reason songs can be transposed to different keys and still sound the same is that the relative intervals remain the same after transposition. Would some song be "adapted" but cannot be played due to a missing black key on the piano?

(For the singer it is still easier than for the piano player to adjust by one half-tone, but pianists are used to that task.)

Note, that for professional solo singers transposition is done on a regular base, to ensure, that the song finely fits their compass, some classical sheet music is even available in different editions for low/middle/high voice. In earlier times with their old tunings the deviations were bigger and the impact on the melody easily recognizable.Īfter leaving the early learning phase behind, the number of accidentals will no longer correspond to the degreee of difficulty (a claim which most players will disagree with anyway). Therefore you can start your song with any white or black key on the keyboard and use the corresponding number of key to the right or left respectively (keeping the intervals the same, a process called transposition) and the melody will remain recognizable.

In order to remove the flat or sharp you need to add a natural, that removes the sharp of flat for one bar and you can add it any where to block or cancel the sharp or flat.As I understand the question, the answer is well-temperedness (one technical term is 12EDO system) or very regular distribution of notes. You can add sharps and flats during the piece that are not already placed at the beginning of the piece. There are two scales that don't have sharps or flats and those are C major and A minor. There are in total of seven flats and sharps, the flat looks like a "b" and the sharp looks like a "#".į sharp, C sharp, G sharp, D sharp, A sharp, E sharp and B sharpĪnd seven flats~.B flat, E flat, A flat, D flat, G flat, C flat and F flat, that is the order that they are placed on a music sheet on both treble and bass clef. There is a key signature for each scale in minor and major scale. They are listed on every line of music, which signifies what key the composer has chosen. This is to avoid the repetition of accidentals in the score. The key signature is something that is in music showing what black key(or sometimes white key, for example, E# or Cb) you need to play and that is sharps or flats.
