I-V chords in C, G, D, A, and F. The pattern I noticed today is that, knowing it’s the fifth that’s shared between these two chords, this is what happens:
- I (root position) – two lower fingers move down
- I6 – outside fingers move down, pivoting around the middle
- I64 – upper two fingers move down
So, when moving from I to V, all movement is in a downwards direction. Wonder what I am going to notice next time?
We discussed the figured bass exercise from Handel. I had no problem naming the chords and inversions. When the chord is closed, the tonic is the note with at least a fourth open below it. The first inversion looks stable, with the thirds on the bottom, and the second inversion looks unstable with the “heavier looking” thirds on top. (I still have to name the notes and figure out the chord when it’s open, but that wasn’t the point of this exercise.) We discussed the fact that some of the chords in the recommended solution did not move to the closest next position, and G- said that was because it’s generally better to move in contrary motion. Also that it was desirable to end on a perfect tonic chord, meaning that the tonic is in both the bass and the soprano (I think), and if I had chosen closest chords all along it wouldn’t have. SO many complications.
Sidetracked by a discussion of seeing keys as patterns, we noted that Mach stops doing transposition after leaving 5 finger patterns. G- suggested I get the MMTA theory workbooks if I wanted to continue graded exercises with more details on transposition and chord progressions.
For next week, I should add E to the list of scales, and also do a I-IV-I-V-I chord progression in each of our keys, starting with each inversion of I. Hmm. so that will be I-IV64-I-V6-I, then I6-IV-I6-V64-I6, and I64-IV6-I64-V-I64. (I need to double check those – just figured them out here at the computer – and realized saying “keyboard” would not have been specific!)
Hokey Pokey went OK, but I still can’t play it smoothly. We worked on the transitions, basically every time I need to move one hand or the other. G- suggested a warm-up where I go up and down one octave of the scale in first inversion chords in the RH while playing the four-note downward motif from G and/or C in the LH. I should spend my practice time working slowly over each transition, simplifying where necessary before playing as written.
Clementi is in similar shape. I can play through the A section slowly (Q=72) but stumble over the transitions for anything faster. My work with blocking the chords for the Alberti bass measures paid off; now I need to repeat that in the B section. Blocking the RH chords in the descending broken thirds passages will probably also be useful. We also reviewed sonata form, and identified the sections and patterns in this sonata.
For next week:
- I-V-I and I-IV-I-V-I patterns in all inversions in C, G, D, A, E, F
- Hokey Pokey (target H=100)
- Clementi Allegro
The best news is that, since S- wasn’t here this week, I get to review this all again next week. I told G- I was grateful for the remedial lesson!
