Lesson transcript:
Left Hand Technique for the B Section
So now let's look at the left hand of the B section. We will use the left hand as if we're comping in the Duke Ellington orchestra.
F6 Chord
- Your left hand will become like the guitar of your piano orchestra.
- F6 chord:
- Triad: F, A, C
- Sixth: D (added with the thumb)
So we have:
- 1 (F), 2 (A), 3 (C), 4 (D) - which makes it an F6.
Going forward, we'll change chords.
F# Diminished Seventh Chord
Now, we move to an F# diminished seventh. It may sound fancy, but it's quite simple from where we are:
- Move your thumb up a semitone to Eb.
- Move your little finger up a semitone to F#.
This gives us:
- F#: little finger on F#, third finger on A, second finger on C, thumb on Eb.
So, we have the chord:
- F# A C Eb (F# diminished seventh).
Chord Progression
First Three Bars
The first three bars are as follows:
- F6: "My darling I guess my mind's more at ease."
- F# diminished seventh chord.
- C Inversion:
- Little finger on G, second finger on C, thumb on E.
Adding C7
Then, we add our third finger on Bb to create a C7 chord.
Recap of Chords
To recap:
- F6: F, A, C, D.
- F# diminished seventh: F#, A, C, Eb.
- C Inversion: G, C, E.
- C7: Add Bb.
Now let's sing the melody while playing the left hand.
Singing and Playing
- 1, A, 2, A.
- 1, 2, 3: "My darling I guess my mind's more at ease."
Next, we return to the F6 but keep the same chord, and this part changes slightly.
E Minor 7 Chord
We'll add a chromatic move here:
- E minor 7: little finger on E, third finger on G, second finger on B, thumb on D.
Chromatic Scale
Now, we move down chromatically:
- D becomes C#, B becomes Bb, G becomes F#, E becomes Eb.
This leads to:
- Eb minor 7 down to D minor 7:
- Notes for D minor 7: D, F, A, C.
Singing and Playing Tempo
I'll sing the melody slowly, so you can watch the left hand.
- Ready? 1, 2, 3, 4:
- "Darling, I guess my mind's more at ease" back to F6, but nonetheless E minor 7: "Why stir up memories?"
Conclusion of Left Hand
That is the left hand of the B section complete.
Adding a Turnaround
At the end, I would like to add a G for a nice turnaround that sets us back into the C chord of the A section.
Full Playthrough
Once again, let's go:
- "Darling, I guess my mind's more at ease" back to F6 but nonetheless E minor 7: while going through semitones, G, D.
I'll play it nice and slow without singing, then you can see what happens in the B section.
- Ready?
Then we're back to A.
Practice Together
Let's take it in turns:
- I'll play the left hand, you play the right hand starting on D:
- "Darling, I guess."
Repeat Practice
- 1, 2, 1, 2, 3, 4: "Darling, I guess."
Now let's swap roles:
- Ready?
- I'll play the right hand, you play the left hand.
Final Playthrough Together
Now, both hands together should sound something like this:
- 2, 2, 3.
Now, when you feel confident, add a bit of rhythm to your left hand.
Rhythmic Touch
Instead of a static chord on "Darling, I guess," add a little rhythm:
- 1, A, 2, 3, 4: Just a little nuance.
You can experiment and have fun with it. Enjoy playing the left hand because that is the rhythm section of your very own orchestra!
