Key learning points

1. In the Baroque, Classical and Romantic periods, tonality was almost always major or minor.
2. Every piece has a key signature, which explains which notes should be used in the given key.
3. Harmony in all three periods is based on primary chords (I, IV and V), with some use of secondary chords.
4. Romantic composers experimented more with chord choice and chromatic notes.
5. Cadences are fundamental to all three periods with perfect and imperfect cadences being the most common.
