In
music, an
interval cycle is a
collection of
pitch classes created from a sequence of the same
interval class. In other words a collection of
pitches by starting with a certain
note and going up by a certain
interval until the original note is reached (e.g. starting from C, going up by 3 semitones repeatedly until eventually C is again reached - the cycle is the collection of all the notes met on the way). In other words, interval cycles "unfold a single recurrent interval in a series that closes with a return to the initial pitch class". See: .
