Background: Learning piano on my own using a method book (alfred's adult series) (88 hours of practice so far), since a month ago. Don't have access to a piano teacher for the moment but will definitely get one as soon as possible.
I'm currently going through a scales book ( Scales, Chords, Arpeggios and Cadences: Complete Book ) and for each key we have:
- Parallel motion in octaves.
- Contrary motion starting on the same note.
- Parallel motion in thirds or tenths.
- Parallel motion in sixths.
- Triads
- Cadences (3 positions)
- Arpeggios (2 inversions + root )
- Dominant Seventh Arpeggios (3 inversions + root)
For each key, I'm currently only concentrating on: scales (parallel and contrary motion), cadences and the first Arpeggios (not the dominant 7th one)).
Question: Does it make sense (from a more traditional piano learning point of view) at this stage to also include the 3rds and 6ths or would it be better to come back them later?
