What are Consonances and Dissonances in Music? John Blow's Through Bass Rules #rules #harmony

Music consists in concords & discords.

The concords that are is a 3d , 5th, 6th & 8th.

Perfect cords is a 5th & 8th.

Imperfect is a 3d & 6th.

Discords are the 2th, 4th, 7th & 9th.

The 9th is the same as the 2d only it is otherways accompanied.

To all counterpoint notes being a semibreis, minim or chrochet (unless a 6th) you must play wth your right hand an 8th, 5th & 3d as it shall happen most convenient to your hand.

Not playing two 8ths or 5ths ascending or decending together.

It is a general rule when your bass ascends to avoid playing 5ths & 8ths in counterpoint your treble must decend towards your bass.

But you may play as many 3d s or sixes ascending or decending11 together as you please they being imperfect cords.
