Harmony note (in this case B, D and F) provide the harmony. In the musical scale, there are twelve pitches. Each pitch is referred to as a "degree" of the scale. The names A, B, C, D, E, F, and G are insignificant. The intervals, however, are not. Here is an example: As can be seen, no note always corresponds to a certain degree of the scale. The "tonic", or 1st-degree note, can be any of the 12 notes (pitch classes) of the chromatic scale. All the other notes fall into place. For example, when C is the tonic, the fourth
Chord-scale system the system. For example, Russell associated the C major chord with the lydian scale, while teachers including John Mehegan, David Baker, and Mark Levine teach the major scale as the best match for a C major chord. Miles Davis's "Lydian Chromatic Concept"-influenced first modal jazz album "Kind of Blue", is often given as an example of chord-scale relationships in practice. The chord-scale system provides familiarity with typical chord progressions, technical facility from practicing scales and chord arpeggios, and generally succeeds in reducing "clams", or notes heard as mistakes (through providing note-choice possibilities for the chords of progressions), and building "chops",
