3Musical Hierarchy TONIC Listen: Her Majesty by the Beatles The importance ofTONICIn tonal music, a key is based on a very important note called a tonic: home base. In a piece of tonal music, it is the tonic note or tonic harmony to which the listener will feel most comfortable returning. Each other pitch in the key (or scale) is defined musically by its relationship to the tonic.Let’s examine each of the scale degrees in this scale.
4Chords in Tonal Music Chords made up only from the notes of the scale Diatonic ChordsAltered Chords / Chromatic ChordsChords made up only from the notes of the scalei.e. All Diatonic Chords in the key of C major would ONLY have white keysChords that may use notes not from the scale.So how are chords used in tonal music?Most chords that you will hear in a given piece of music
5Before we compose with these chords, we are going to learn how to recognize them.
6Return to scales for a moment…. Minor ScaleMajor ScaleHarmonicNaturalMelodicYo the major scaleThere are indeed various forms of the minor scale, however, composers do not think about the various forms when they compose. Rather, let’s think about the minor scale as 1 singular collection of pitches that simply has 2 variable scale degrees: 6 and 7.
7A unified minor scaleAll minor scales can be thought of as an alteration of the natural minor scale seen here.Harmonic is the natural minor scale with a raised 7th scale degree.Melodic is simply the natural minor scale with a raised 6th and 7th scale degree going up.So scale degrees 6 and 7 are the only variable item here. The only note that will change.
8How composers use the various forms… D natural minor – D E F G A Bb C Dharmonic D E F G A Bb C# Dmelodic D E F G A B C# D
9When to use raised/lowered 6 and 7 More natural to raise 6 and 7 going up (ascending)A single raised 7 indicates a return to the tonic (usually)More natural to lower 6 and 7 going down (descending)Let’s look at an example…..
