C#maj9 Piano Chord

C#maj9 is the C sharp major ninth chord, usually written Dbmaj9 on real charts. It has five notes: C sharp, F, G sharp, C and D sharp, and it spans a ninth, so the root usually goes to the left hand.

C sharp at the bottom, then F, G sharp, C and D sharp. Give the root to the left hand if the span is too wide; the top four notes sit comfortably in the right.

How to play C#maj9 on piano, step by step

Start on the C♯ above middle C. That is the lowest note of the chord.
Thumb (1): C♯
Index finger (2): F
Middle finger (3): G♯
Ring finger (4): C
Little finger (5): D♯
That reach is wider than an octave, so most players split it: play C♯ with the left hand and the other notes with the right. If you keep it in one hand, leave out the fifth (G♯), the note the chord misses least.

Two notes read oddly here: the third is strictly E sharp and the seventh B sharp, but charts print the plain F and C you actually press. Same keys, simpler names.

If it sounds wrong

The stretch is too wide: Play C sharp with the left hand and F, G sharp, C and D sharp with the right. Ninth chords are meant to be shared between hands.
The seventh sounds wrong: The seventh here is the white key C, one half step below the octave C sharp. Pressing B instead gives the flat seventh and a completely different, pushier chord.
The chart says Dbmaj9: Same chord. D flat and C sharp are two names for one key, and the flat spelling is the more common one in print. Every key you press is identical.

What makes it a C#maj9

C♯ · F · G♯ · C · D♯ 1 3 5 7 9

C#maj9 is C#maj7 with a ninth added: C sharp, F, G sharp and C make the major seventh chord, and the D sharp on top makes it a ninth. Strict spelling calls the third E sharp and the seventh B sharp; the keys under your fingers are F and C.

It is the I chord of C sharp major at its softest, and in print it almost always appears as Dbmaj9, because D flat is the friendlier way to write this key. R&B and neo soul live in exactly these keys.

C#maj9 vs C#maj7

C#maj9 is C#maj7 with a D sharp on top. The seventh chord rests; the ninth adds width and a little haze above it.

In the hand it is one more note and a reach past the octave, so it is usually split between hands where C#maj7 is not.

Questions about C#maj9

Is C#maj9 the same as Dbmaj9?

Yes, one chord with two names, and Dbmaj9 is the spelling most charts use. The keys you press are identical.

Which notes are in a C#maj9 chord on piano?

C sharp, G sharp and D sharp on the black keys, plus F and C on the white keys. The F stands in for E sharp and the C for B sharp.

What is the difference between C#maj9 and C#9?

The seventh. C#9 has B natural, the flat seventh, and pushes toward F sharp; C#maj9 has the C a half step under the octave and stays put.

Why are there no inversions on this page?

The chord is wider than an octave, so an inversion of it does not stack cleanly; the moved note lands inside the chord. Pianists use rootless voicings for that instead, an advanced topic this page leaves alone.

Do I have to play all five notes?

No. Leave out G sharp, the fifth. C sharp in the left hand with F, C and D sharp in the right keeps everything that makes the chord.
