Have you ever wondered what you would do with a massive data set of 100's of 1000's transcribed and annotated music? What if those transcriptions were rated by users all over the world?

Well, I and a few others were wondering, so I created a hypothetical scraper that will generate a Neo4j database of Guitar Pro files locally donwloaded, linked to metadata around each file.

What features are captured?

Tab Files/Nodes

  • Relative file location of the guitar pro file
  • Rating of the tab
  • Number of ratings the tab recieved
  • Number of comments on that tab
  • Views of that tab
  • Properly nested comments, whith ability to track the users commenting in the graph id you wanted
  • Title
  • Version
  • Instruments in the GP file

User nodes

  • Name
  • Number of contributions
  • Ranking
  • Join date
  • Can be linked to comments easily (but isn't at the moment)

What can I use this for?

Guitar pro files have some seriously awesome metadata associated with them:

  • Multiple instruments
  • Time signatures (good for segmenting)
  • Repeat notations (good for segmenting)
  • More nuanced notation for instrumetns (bends, slides, vibrato, etc)
  • Instrument tuning, incuding capo
  • Sometimes musicians are labeled on the individual tracks
  • Track Metadata
  • Convertable to MIDI
  • Occasionally lyrical content

Most of this can already be done with open source code (tux guitar in java, and there exists a really neat ruby library for reading gp3/4/5. This is just a project for hypothetically gathering the data for further feature extraction.

This code doesnt work/How do I make it work

I don't know! It's purely hypothetical. It supports tab downloads based on a hypothetical security feature involving a salted SHA1, that's about all I can figure out. The code is fairly well commented/named, if you are intelligent, you might be able to make use of it.

##DISCLAIMER: I TAKE NO RESPONSIBILITY FOR WHAT YOU DO WITH THIS HYPOTHETICAL CODE EXPERIMENT! IT IS PROVIDED FOR EDUCATIONAL PURPOSES ONLY, WITH ACADEMIC STUDY IN MIND. I have never run this code on any commercial database.
