This is an old post, but it has many visits, so I'll venture an answer for any future visitors.
...I’m just a beginner having a hard time reading stuff fast.
This should be addressed first. This piece looks easy, but obviously the harmonies are not. Also, in terms of touch, dynamics and balance, it isn't easy to play well. It might make sense to work on some easier pieces first. If you wanted to stay with Satie, look at the Ogives, they are easier, shorter, and will provide an introduction to Satie's harmonic style. Also, there are tons of short, easy etudes and character pieces from the later nineteenth century at imslp.org which might be good alternatives.
About the Gymnopedie #1. There isn't a simple pattern like it's all roots by descending fifths, or sequential harmony. But I think it can be broken down into segments to aid memorization and reading.
From m. 22 to the end I identify 4 main phrases:
- one 5 bar phrase
- a second 5 bar phrase, last three bars are the same chords as the previous 5 bar phase, and both 5 bar phrases work over a long
D
pedal in the bass.
- third phrase is ending #1, 5 bars with a 3 bar
II V I
cadence
- fourth phrase is ending #2, 5 bars with a 3 bar
II V I
cadence, the second ending involves a mode change to minor and an E
pedal in the bass.
So, we do have some repeating elements, even if they are not super obvious patterns. There are two pedals involved, and the 4 phrases utilize repeated material for their endings.
m22. /---------------------\
Am | Em7/D | Em7/D | Dm9 | Dm7 |
--D pedal -----------------------
m.27 /--same as mm.24-6 ---\
Dm7 | Dm9 | Em7/D | Dm9 | Dm7 |
D pedal -------------------------------
m.32 ending #1 /---II V I--cadence--\
Em | F#m | Bm | A/E | F#m7/E| Em11 | Am7 | D |
\--root pos. triads--/ \---inverted---/
m.40 ending #2 switch to minor mode /---II V I--cadence--\
Em | Dm | F(maj)| Am | F(maj)| Em11b9| Am7 | Dm |
\---E pedal--------------------------/
That still seems complicated, but we could try to abstract it further to find the harmonic "anchors" and then what is harmonic elaboration.
The tonic is D
. Mm. 22-31 essentially juxtapose Em
and Dm
over a D
pedal, which is a lot of dwelling about the tonic. Mm. 32 to the end then elaborate the cadences Em Am D(m)
with the important mode switch to minor that effects the chords preceding the cadences.
Abstracted...
- 5 bars juxtaposing
Em
and Dm
over a D
tonic pedal
- 5 bars juxtaposing
Em
and Dm
over a D
tonic pedal
- 5 + 3 bars
Em...
to cadence Em Am D
major mode
- 5 + 3 bars
Em...
to cadence Em Am Dm
minor mode
...that allows use to see just the stuff for roots E
, A
, and D
which of course are the important tonal degrees for tonic D
. The details that have been abstracted away should be understood in relation to this tonal foundation.
When I learned how to play (pretty poorly) this piece I spent a month memorizing it phrase by phrase. But I hadn't done this harmonic structure analysis, so I promptly forgot it soon after moving on to the next piece. I can't say this harmonic structure analysis will actually be helpful for memorization, but if I were to work on this piece again, I would approach it this way. Not just to aid performance, but to study composition and emulate Satie's style.
