Ways to accompany with C7
Same chord, five rhythms. The pattern changes the style more than the notes.
| Pattern | Notes | Good for |
|---|---|---|
| Block chord | C+E+G+Bb | learning a new song, hymns |
| Shell: root and seventh | C+Bb | comping under a singer |
| Root, third and seventh | C+E+Bb | jazz and soul, the full colour in three keys |
| Root and fifth | C+G | driving rhythms, a strong open sound |
| Octave bass | C+C | loud endings, big chorus |
C7 for the left hand, position by position
Finger 5 (little finger) always takes the bottom note. Keep the hand low, near middle C but below it: lower than that the chord gets muddy. Black keys: Bb (finger 1). White keys: C E G (finger 5, 3, 2). Move the hand slightly in so the fingers on black keys do not slip.
| Position | Notes, bottom up | Fingers |
|---|---|---|
| Root position | C E G Bb | 5 3 2 1 |
| 1st inversion | E G Bb C | 5 3 2 1 |
| 2nd inversion | G Bb C E | 5 3 2 1 |
| 3rd inversion | Bb C E G | 5 4 2 1 |
Both hands on C7
Over C7, the safest right-hand notes are the chord notes C E G Bb; scale notes between them work as passing notes.
If both hands play the same notes in the same octave the sound gets thick: leave a gap.
Change from C7 without jumping
Do not play every chord in root position: the hand would jump. These positions move one or two keys at a time.
| Chord | Left hand plays | Keys that stay |
|---|---|---|
| C7 | C E G Bb (Root position) | starting chord |
| F | C F A (2nd inversion) | C |
| Bb | D F Bb (1st inversion) | F |
| C7 | C E G Bb (Root position) | Bb |
A left-hand routine for C7
- Find C below middle C with finger 5 and drop the hand on C, E, G and Bb.
- Go through the patterns in the order of the table: block chord; shell: root and seventh; root, third and seventh; root and fifth; octave bass.
- Loop C7 → F → Bb → C7 with the positions above, eyes on the music, not on the hand.
- Last, add a simple right-hand note on top: the left hand should keep going on its own.
Come back tomorrow and start from the pattern you found hardest today.
Train C7 against the clock
ChordRunner shows a chord symbol and checks the notes you play, in any octave and any position, so a left-hand C7 counts. Plug in a MIDI keyboard or use the microphone with an acoustic piano.
Play the demoCommon questions
How do you play C7 on piano with the left hand?
Put finger 5 on C below middle C and play C, E, G and Bb with fingers 5 3 2 1.
Which C7 position is best for the left hand?
The one closest to the next chord. In C7 → F → Bb → C7 the hand plays C7 = C E G Bb; F = C F A; Bb = D F Bb; C7 = C E G Bb.
Why are left-hand fingers different from the right hand for C7?
Because the hand is mirrored: the little finger (5) sits on the bottom note C and the thumb on top. The right hand would play the same notes with 1 2 3 5.
Does a game count C7 if I play it low with the left hand?
In ChordRunner, yes: the game listens for the notes C, E, G and Bb, not for a hand or an octave. Use a USB MIDI keyboard, or the microphone with a real piano.
Your instrument is the controller.
ChordRunner is a browser game that teaches piano and guitar chords: a chord appears on screen, you play it on a real instrument, and your runner jumps. MIDI keyboard or microphone, both work.
