Chord & FretC#m7 · Guitar
End of the workday, headphones on, the bus moving slowly — and, strangely, everything's fine. That state of mind has a chord symbol: C#m7. Give the audio below a listen and recognize it.
Listen first
What you just heard
The recipe: take the C#m you know — C#, E, G# — and add B on top. Play the arpeggio again, no rush and wait for the fourth note. It doesn't make the chord happy; it takes the weight off its shoulders. That's why bossa nova, neo-soul and the whole of R&B live here.
Now it's your hands' turn
On the guitar, six strings give the chord room to breathe — some positions use them all, others ask you to mute the lowest ones. So start with the first position below — the position marked with ⭐ is the easiest to play. Four notes sharing the same space, so there's one rule: every single one has to ring. Go note by note, like checking signatures. A muffled chord here is a double waste.

Mid-neck positions are the favorites of anyone backing a singer: they leave the treble free for the voice. File it away for that day.

What is C#m7?
C#m7: C# minor with Seventh. The notes are C#, E, G#, B (fixed-do: Do#, Mi, Sol#, Si) — the degrees 1–b3–5–b7.
Where this chord lives
Now the part beginners rarely get told: C#m7's classic job is being the ii — the first piece of the ii–V–I, the most-used sentence in jazz and everything jazz ever touched. Across keys you'll find it as i7 in C# minor, v7 in F# minor, iv7 in G# minor. In other words: this chord is almost never standing still; it's setting something up.

Where it tends to go
Treating C#m7 as the home chord (I) of its key, it usually moves toward the pre-dominant (D#m / F#) or the dominant (G# / B#°) — and the dominant pulls back home. Typically, not a rule.

When you want to go further
For improvising, C# Dorian (C# D# E F# G# A# B · 1 2 b3 4 5 6 b7: the minor scale with a major sixth — the minor that smirks); C# Aeolian (C# D# E F# G# A B · 1 2 b3 4 5 b6 b7: the natural minor, the major scale's relative sibling); C# Dorian ♭2 (C# D E F# G# A# B · 1 b2 b3 4 5 6 b7: a dorian with a lowered second) contain the whole chord. And the jazz shapes at the bottom are these same four notes rearranged across the neck: same chord, arranger's tailoring.

Improvising in context
To improvise over C#m7 as home, the C# Aeolian scale fits entirely — it contains every note of the chord. And when the dominant (G#) pulls back, the leading tone C is the note that wants to resolve home.
Swaps that work:
- Emaj7 — Relative major (♭III)
- Gb7 — It's the ii; resolves to this V
