A few half-diminished permutations to get started
Not to worry! In this post, we'll cover just a few of the permutations of just four notes - which yield the measly number of 24 possible unique combinations - definitely enough to deal with!
The 4-note cell focused on here is commonly known as a min7b5, or half-diminished chord and is similar in concept to a previous post and book, "Permutation Station 1235".
