About A# augmented
A# augmented is built from three notes: A# (root), C## (major third) and E## (augmented fifth). Its interval formula is 1 – 3 – #5. Its augmented fifth gives it a restless, mysterious sound, and because it is symmetrical the same chord repeats every four semitones.
A# augmented has no standard open shape in the CAGED system, so its 24 voicings are sorted only by difficulty and position on the neck. Another way to write A# augmented is Bb augmented (the same piano key, with a different name). The usual choice is Bb augmented.
