For instance the function of the aforementioned lydian dominant would be more likely found played over a V+11 than to actually emphasize the mode itself. It's worth noting most of the Jazz scales commonly named after modes aren't necessarily used in a "modal" way. Both half-whole and whole-half variants suffer this. Something needs to give in order to fill in the gaps without an augmented unison, so this scale will contain a C♯ as the 7th step in order to have an interval of a second between each step while still outlining the correct diatonic chord. Say we're in Cmin and want to play a diminished scale over the ii. Diminished scales are also frequently impossible to write without a sharp and flat. Lydian dominant is a nice self-explanatory one - contains a ♯4 and ♭7. Pick up any Aebersold book and head to the scale syllabus and you'll find some examples. If it is a WHOLE STEP below the tonic, it is still considered the SUB TONIC but not a LEADING TONE.Sticking with diatonic harmony, the most common examples are going to be scales that outline some extended harmony because there can be multiple altered chord factors which are either nonsensical or impossible to spell without a sharp and flat due to their function relative to the key. It is only considered the LEADING TONE when it is a HALF STEP below the tonic. It often precedes tonic in a chord progression.Ħ) SUB MEDIANT- Scale degree 6 is the same distance below the tonic as the mediant, scale degree 3, is above the tonic.ħ) SUB TONIC or LEADING TONE- The note below (and that often precedes) the tonic, in a chord progression. This note is second most important note only to the tonic. This is the middle, or "third", of a triad.Ĥ) SUB DOMINANT- Scale degree 4 is the note immediately below the dominant.ĥ) DOMINANT- Scale degree 5 is roughly at the center of the scale. The C note is the tonic of the C scale.Ģ) SUPER TONIC- Scale degree 2 is the note above the tonic.ģ) MEDIANT- Scale degree 3 is the midpoint between the tonic, scale degree 1, and the dominant, scale degree 5. This is the note for which the scale is named. 1) TONIC- Scale degree 1 is the root, or the foundation, of the scale.
