For example, in a woman with a 21-day cycle, the follicular phase is likely seven days; in a woman with a 35-day cycle, the follicular phase is likely twenty-one days.

The diatonic scales. The diatonic scale is most familiar as the major scale or the natural minor scale (or aeolian mode). The diatonic scale is a very important scale. Out of all the possible seven note scales it has the highest number of consonant intervals, and the greatest number of major and minor triads.he diatonic scale is a very important scale.

The word chromatic actually means colourful - the scales are very colourful since they use ALL 12 different notes available instead of just 7 of them! The scales you have studied up till now-major and minor-are in a group called diatonic scales.Diatonic scales all contain 7 notes and are firmly based on a key-and the keynote, or the first note of the scale, is the TONIC. Chromatic scales are not in any particular key.he notes we have found are Eb, D, Eb, E, F. The E flat is repeated, so we should ignore the first one, which will give us four notes in total: D-Eb-E-F. These are four consecutive notes which are part of a chromatic scale.
