The A# natural minor scale is a seven-note scale that consists of the notes A#, B#, C#, D#, E#, F# and G#. It follows a specific pattern of whole and half steps: whole, half, whole, whole, half, whole, whole. This scale is often used in various music genres, providing a darker and more somber sound compared to major scales. In music theory, the natural minor scale is one of the three types of minor scales, alongside the harmonic and melodic minor scales. The A# natural minor scale is the relative minor of the C# major scale, sharing the same key signature of four sharps.
