I used two reasonings, and always ended with a slightly cryptic message, namely
CACHED.
The first method was to look up this chart
http://www.ultimatesongwriting.com/wp-content/uploads/2017/01/saxophone_fingering_chart.png
and using the six bottommost circles of the patterns in "part 2", I interpreted the message as
"CACBED", which made no sense, until I remembered that a "B" is actually called "H" on the German scale
The other method was a brute force dictionary attack on a substitution cipher. First, I read the data as columns, because reading it as lines would give the same letter three times in a row. Then, the pattern of the letters is "121345".
Assuming that the music theme is of some relevance, I then searched my spell checker word list (Ubuntu's "british-english-insane", with the last bit referring to the number of words included) for words consisting of names for musical notes that match the letter pattern "121345". I found two, and the other one was "AFACED", which isn't really a dictionary word. The other match was, of course, the same word as found by the other method.
Std. disclaimer: I may very well have made a mistaken assumption somewhere along the way, since the resulting message is a bit opaque, to say the least.
