In today’s lesson we’re looking at Bach’s Invention no. 1, the first out of a collection of 15 written in 1720. We’ll be looking at the full piece: the subject, the motifs, the rhythm, the harmony and the structure because there is so much to learn!
The riff is a short and catchy melodic idea and it recurs so often that it gives character and structure to a song. The hook is any part of a song that is meant to grab the listener’s attention. The hook is also catchy but it doesn’t recur as often so that it makes a greater impact when it turns up.
There are 15 different key signatures in music so how do we figure out which ones have sharps and which ones have flats? How do we know how many sharps and flats they have? And where do the minor keys…
In total, there are 12 major scales because the major scale pattern can begin on any of the 12 notes of the musical alphabet.
There are 3 minor scales, or more precisely, 3 variants of the minor scale because of how harmony and melody interact in tonal music. Composers change some notes of the minor scale to achieve a specific sound for a particular style.
