FAQ

Transposition is shifting all the notes in a piece of music up or down by a fixed interval. This changes the key while keeping the relative relationships between notes the same.

Common reasons include: matching a singer's vocal range, making a song easier to play on an instrument, matching keys for DJ mixing, or adapting music for different instruments.
