Music on the planet Alpha Lyra IV consists of only two notes, called A and B. Also, songs never include three consecutive repetitions of any sequence nor does BB ever occur. A sequence of notes can have 1 or more notes in it.
What is the longest song on Alpha Lyra IV?
(In reply to Question
by Michael Cottle)
Consider a song to be a sequence of notes without regard to how long each note is held.
For the purposes of this puzzle you can assume that all notes are quarter notes, or eighth notes, or even hemidemisemiquavers, if that tickles your fancy.
