Odd harmonic: Difference between revisions

Line 1:

An '''odd harmonic''' is a [[harmonic]] where the [[frequency ratio]] is an odd number. The first few odd harmonics are [[1/1]], [[3/1]], [[5/1]], [[7/1]], [[9/1]], [[11/1]], etc. Odd harmonics are significant in that they create distinct [[pitch class]]es, since any even harmonic is a whole number of [[~~2/1|~~octave]]s above an odd harmonic.

An [[odd limit]] is the set of all [[just interval]]s where the largest odd factor in the numerator and denominator both do not exceed a specified bound. For example, the [[5-odd-limit]] consists of all ratios where the only allowable odd factors are 1, 3, and 5; those being [[1/1]], [[6/5]], [[5/4]], [[4/3]], [[3/2]], [[8/5]], [[5/3]], and any whole number of octaves above those intervals.
