A#m ukulele chord
A#m (A sharp minor) is built from A#, C# and E#, the degrees 1–b3–5. On ukulele, the main shape is 3 1 1 1, the first diagram, marked with the star. It sounds the same as B♭m (Bb, Db and F), the usual name in flat keys.
From A# major to A#m, a single note moves — and it feels like the season changed. Hit play below and check.

Why A#m sounds this way
The trick is smaller than it sounds. Two of the three notes didn't move: A# and F stayed put. Only the middle one dropped — a half step, the smallest distance in music — and became C#. Now listen to the arpeggio, one note at a time and stop at the second note. That's the one. Half a step separates a sunny day from a Monday morning.
How to play A#m on ukulele
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 — it's the main shape — that's why it carries the ⭐. And do the exercise that's worth a whole lesson: A# major, then A#m, then major again. Back and forth ten times, slowly. Your ear learns the difference before your brain does.

Where A#m shows up
In real music, A#m works almost always as v in D# minor, i in A# minor, ii in G# major. In pop everywhere it tends to be the famous vi — the chord the chorus runs to when it wants to get serious without changing key. You've heard it a thousand times; now you'll start noticing it.

Where A#m usually goes
Treating A#m as the home chord (i) of a minor key, it tends to go toward the pre-dominant (D#m) or the dominant (E#7, from harmonic minor), and the dominant pulls back home. Typically, not a rule.
Going beyond A#m
When it's time to improvise, A# Dorian (A# B# C# D# E# F## G# · 1 2 b3 4 5 6 b7: the minor scale with a major sixth — the minor that smirks); A# Aeolian (A# B# C# D# E# F# G# · 1 2 b3 4 5 b6 b7: the natural minor, the major scale's relative sibling); A# Phrygian (A# B C# D# E# F# G# · 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.
