Google Books for music - example of data representation and desired query

gistfile1.txt

# In the following example I show how I set up my river and GET a sample document. Music is represented as an array of 
# neumes. Every neume has a name, location (specified in box coordinates - [lower right y, upper left x, upper left y,
# lower right x]), and a sequence of pitch names.  The goal is to be able to return the appropriate box coordinates for
# either a series of neume names or a sequence of pitches. So, in the given example, a user could search for the nueme 
# sequence "punctum, scandicus, clivis" and the returned result would contain the box coordinates for that 3-neume
# sequence ("location": [9,0,14,12]). The user could also search for the pitch sequence "c, a, f" and the returned result 
# would contain the box coordinates for the neumes containing that sequence ("location": [9, 6, 7, 12]).
