C sharp major 7th chord inversions
A seventh chord has four notes, so it has four positions. Each one is still C#maj7.
Root position: C# E# G# B#
1st inversion: E# G# B# C#
2nd inversion: G# B# C# E#
3rd inversion: B# C# E# G#
Playing C#maj7 with each hand
| Hand | C# | E# | G# | B# |
|---|---|---|---|---|
| Right hand | 1 (thumb) | 2 | 3 | 5 (little) |
| Left hand | 5 (little) | 3 | 2 | 1 (thumb) |
Play C#maj7 broken first, C#, E#, G#, B# one by one, then together: a wrong key stands out.
The light version of C#maj7
The fifth (G#) adds little colour. C# E# B# is enough to sound like C#maj7 and is far easier to reach.
Four 7th chords on C#
Play the four in a row and listen to each colour.
How to practise C#maj7
- Start in root position: C#, E#, G#, B#, four times, eyes on the symbol.
- Walk up through the inversions (E# G# B# C#, G# B# C# E#, B# C# E# G#) without lifting the whole hand.
- Loop D#m7 → G#7 → C#maj7 until the change into and out of C#maj7 is clean.
- Finally meet it in random order between other chords, with a check on every note.
Short daily rounds fix C#maj7 in memory faster than one long practice a week.

Play the demoCommon questions
What is the difference between C#maj7 and C#?
C#maj7 adds one note to the C# triad: B#, the major seventh. That fourth note is what makes it a seventh chord.
Can I play C#maj7 with three notes?
Yes. Leave out the fifth and play C# E# B#: root, third and seventh. It still sounds like C#maj7 and is easier for the left hand.
Where does C#maj7 go?
C#maj7 is the Imaj7 of C# major and the IVmaj7 of Ab major (as Dbmaj7). It is where a ii-V-I in C# major lands: D#m7 → G#7 → C#maj7.
Can I practise C#maj7 with a MIDI keyboard?
Yes. In ChordRunner a USB MIDI keyboard is detected automatically, and an acoustic piano works through the microphone. C#maj7 counts in any inversion, as long as C#, E#, G#, B# sound together.
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.
