The use of counterpoint and fugue decreases during the baroque period. Counterpoint is a musical technique that involves combining two or more melodies together, usually in different voices. Fugue is a musical composition that consists of one theme with several variations on it, each with its own key.
Monody and concerto grosso increase during the baroque period. Monody is a solo vocal piece, while concerto grosso is an orchestra piece performed by a small group of musicians in contrast to an opera which uses large groups of musicians.
The tonality becomes more important during the baroque period. Tonality refers to the relationship between chords in a piece of music and their placement within the key signature. For example, if a piece has three chords but only one chord has been altered from its original form then that chord would be considered as being out of tonality with the others because it does not belong in this key signature; therefore making it sound dissonant rather than harmonious when played alongside them (Dove).
