The A# Major chord is a bright, stable major triad — one of the first chords most players learn. It is built from the notes A#, D, F. This page shows how to play A# Major on Mandolin with clear fretboard diagrams and suggested finger positions.
The lowest shape sits at fret 3 and spans 4 frets, with no open strings in it. A# falls on the G string. It sounds from A#3 up to A#5.
Mandolin is strung in four courses of two, each pair tuned in unison, so each stopped note here sounds as two — which is why the shape rings thicker than the same grip on a single-strung instrument.
Browse alternate voicings to find the one that sits best under your fingers, then compare it with the other chord types built on A# or explore the same shape in nearby keys. The diagrams list the notes in each voicing so you can connect the shape to the theory behind it.
