Harmony and Scale Theory

Harmony & Scale Theory
- concepts of minor and major (which most of them will probably know).
- avoid notes in both of these types of keys (e.g. 4th in the tonic major, or 6th in the tonic minor)
- cycle of 5ths
- what kind of 7ths to use and when to use them (3 types: major, minor, dominant)
- passing notes

Avoid Notes:


Degree
Major
Minor
Tonic
4th
6th, b7th
Supertonic
4th
Sub-dominant
6th
Dominant
1st
7th
Relative Minor/Major
4th
1st

This table displays the 'avoid notes' (notes which when improvising it is unconventional to use as accented) for each degree of the scale.
