I hear the following in string parts a lot in intense movie scenes or certain styles of music. I don't think that this falls under the categorization of Alberti Bass since it's functioning as a melodic part and not a bass part. You can assume that the main chord for this example is A minor, but of course, it doesn't have to be, but that's the chord I intend when I show this. Basically, on beats and the "+" and
of beats chord notes and non-chord notes are played interrupted by the 5th of the chord. This note that alternates on the e
and a
if one was counting 1e+a
can also be the root of the chord from what I've observed. Any ideas on how to categorize this?
Update: the pattern is not repeating.
