215. By transposition is meant playing, singing, or writing a piece of music in some other key than the original. Thus e.g., if a song written in the key of G is too high in range for a soloist, the accompanist sometimes transposes it to a lower key (as F or E), thus causing all tones to sound a second or a third lower than they did when the same song was played in the original key.
