Why Is There No B Sharp Or E Sharp?
B sharp and E sharp exist in music, but we don’t use them very frequently because they are the same pitches as C and F, respectively. In Western music history, It is thought that the natural notes (C, D, E, F, G, A, and B) were first defined, and that accidentals (sharps and flats) were an afterthought to this.
In Western musical notation, the symbol ‘#’ indicates that the pitch of the note should be raised by one half step. The natural notes in the diatonic scale take up an uneven amount of space in the frequency spectrum. There wasn’t enough space in the spectrum to add pleasing-sounding notes in between B and C, and C and F.
Not every culture uses the same musical notes as the ones found in Western music. The concept of musical notes and scales is a relatively recent development in the history of music. Different cultures have developed their own systems for organizing and representing pitches that they deemed pleasing to the ear.
For example, in Indian classical music, pitches are organized according to a system of 22 microtones that they call shruti. This demonstrates that our concepts and understanding of scales are an arbitrary development based on our culture.
