Voicing (music)

In music theory, voicing is "the manner in which one distributes, or spaces, notes and chords among the various instruments" or "simultaneous vertical placement of notes in relation to each other." It includes the instrumentation and vertical spacing and ordering of the musical notes in a chord: which notes are on the top or in the middle, which ones are doubled, which octave each is in, and which instruments or voices perform each note.
