Hey there,
recently I purchased the Beato book (I saw his name mentioned here before, but in case you don’t know: essentially it is a book where you can find a lot of scales and chord diagrams, things about chord progressions and general music theory etc.) because of a great discount that he offered. I already knew that this is not like a comprehensive course but more like a sort of reference book.
I bought it mainly to increase my knowledge about chord progressions and chord shapes because I would like to be able to use more unique chord shapes for improvisation (I mean, if you read a simple A minor chord, it is very awesome what you can do with these three notes if you play that one chord in different inversions and voicings).
The chord diagrams in this book are helpful, however, since I want to increase my repertoire with shapes of seventh chords, it is a bit overwhelming at the moment. There are about 70 pages with nine diagrams per page about drop 2 and drop 3 voicings alone, which makes roughly about 600 shapes. That is impossible to memorize (although I am aware of the fact that some of them, like a diminished major 7 chord, are seldom encountered).
I know how these chords are built and where to find the intervals, but that takes a few seconds to think about and it is at least likely that I can not come up with a shape that is easily playable on the fly. That was my intention with just memorizing some of them.
Is the memorizing process a bad idea? How would you go about learning them? I also thought about writing some riffs where I focus on maybe just two inversions of a specific chord and try to play that on different stringsets, which seems so far to be the most meaningful way.
