A standard musical instrument, such as a piano, has the keys of the accidental notes coloured such that the same note in each octave is the same colour (ie the key C sharp/D flat is the same colour in all octaves). Such a musical instrument can be played in conjunction with a standard musical notation in which all the accidental notes are coloured so as to correspond with the equivalent keys of the musical instrument. Thus, for example, all instances of C sharp and D flat are coloured the same as the above mentioned key. |
