Like the key of C# major, A# minor has all seven of it’s tones sharped. Here is the scale.
The chords that occur in A# minor are shown below.
Here, the chords in the key are shown with guitar diagrams added above. Notice that in the second chord diagram, it is showing a “c dim” chord. Technically this is the same as a “B” that has been sharped due to the fact that the distance from “B” to “C” is a half step. (one fret) This sometimes confusing reality is also the case with the notes “E” and “F”. This is a one fret gap as well.
