Cm · Ukulele

Turn off the living-room light without moving a thing. Same furniture; different mood. That's exactly what Cm does to C major. Press play down there and watch the light go out.

Listen first

What you just heard

The trick is smaller than it sounds. Two of the three notes didn't move: C and G stayed put. Only the middle one dropped — a half step, the smallest distance in music — and became D#. Go back to the audio and catch the arpeggio note by note and stop at the second note. That's the one. Half a step separates sunshine from drizzle.

Now it's your hands' turn

On the ukulele, the high reentrant G makes every shape light — and with four strings, every note is exposed. So the first position below is your way in (1 open string helping) — it's also the easiest one to play. And do the exercise that's worth a whole lesson: C major, then Cm, then major again. Back and forth ten times, slowly. Your ear learns the difference before your brain does.

Once the first shape comes out without thinking, the positions below are waiting. That's where Cm lives in songs that roam the neck.

What is Cm?

Cm: C minor. The notes are C, Eb, G (fixed-do: Do, Mi♭, Sol) — the degrees 1–b3–5.

Where this chord lives

In real music, Cm works almost always as i in C minor, v in F minor, iv in G minor. In global pop it's the famous vi: the serious detour a chorus takes without leaving the key. You've heard it a thousand times; now you'll start noticing it.

Where it tends to go

Treating Cm as the home chord (I) of its key, it tends to go toward the pre-dominant (Dm / F) or the dominant (G / B°) — and the dominant pulls back home. It's a tendency, not a law.

When you want to go further

To solo over it, C Dorian (C D Eb F G A Bb · 1 2 b3 4 5 6 b7: the minor scale with a major sixth — the minor that smirks); C Aeolian (C D Eb F G Ab Bb · 1 2 b3 4 5 b6 b7: the natural minor, the major scale's relative sibling); C Phrygian (C Db Eb F G Ab Bb · 1 b2 b3 4 5 b6 b7: the minor with a lowered second — a Spanish seasoning) work in full. The swaps below are the chord's cousins: different color, same job.

Scale — The whole scale on the neck — in boxes or 3 notes per string; on the major modes, on guitar in standard tuning, with the CAGED forms named · see it in Chord & Fret

Improvising in context

To improvise over Cm 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 B is the note that wants to resolve home.

Swaps that work:

• Ebmaj7 — Relative major (♭III)
• F7 — It's the ii; resolves to this V

This chord has a calmer sibling: Cm7. Same seriousness, relaxed shoulders — worth the visit.
