A semantic and technical analysis of musical scores based on Information Retrieval and SQL principles

OVERVIEW: Modulo7 is an research attempt to build a purely objective music analyzer Music Information Retrieval Engine

using music theory, natural language principles and big data principles along with a SQL like querying interface.

Most Music recommendation engines take into account user feedback for recommendation and analysis

purpose and does not take into account music theory. Modulo7 allows comparisons based on both 

simple and complex rules of music theory and would eventually allow extensible rules to be defined 

by users for comparisons. Standard Users will be able to use simple rules for recommendation and statistics

mining, and power users would be able to define their own custom rules for ranking/search and querying. I hope this paradigm

shift will allow a faster recommendation engine, statistics mining and Music Information Retrieval in general.

Modulo7 will also support a query engine and a big data distributed database like format(using HDFS) and a unified representation

for all forms of music (using a domain specific conversion followed by a serialization via Avro).

Typically a query on this engine will be sql like. An example query will be of the format:-

e.g. ) select sheet_music from MUSIC_DATABASE where melodic_complexity > some value

The measure melodic_complexity is a defined parameter for sheet music format and the above query will acquire all such

songs from the database.

(MODULO7 IS A RESERACH PROJECT AND FOR INTENDED FOR PRODUCTION USAGE).

Modulo7 has the following broad goals:-

1. A vector space model for music representations. These models will represent music in an abstract form

on which standard and customized rules based on music theory can be applied. Concepts like phrasing analysis,

timber and pitch analysis and custom rules (e.g - a higher number of power chords implies chances of the music 

song being a rock or metal song). The vector space model will include custom similarity measure

and extensible similarity measures based on user input on complex music theory rules (STATUS : COMPLETED)

THIS COMPONENT IS THE BULK OF THE WORK AND THE NOVELTY OF THE PROJECT.

2. An acoustics source parser component. The acoustic parser takes files like (.mp3, .midi) etc

and acquires note, pitch, key and other forms of information from the files. These will be then feed 

to the vector space model component. (STATUS : COMPLETED)

3. A sheet music miner component. The sheet miner will take western music sheets of the

form (.png, .jpeg etc) files and extract the notes, key signature from the images. This information

can then be used to create a (STATUS : COMPLETED)

4. A music xml parser component : It takes files of music XML format and parses the relevant information

from them. (STATUS : COMPLETED)

5. A lyrics analyzer : The lyrics analyzer will take its input from the crawling engine and then make objective

analysis on the lyrics (e.g the vocabulary richness of the song, semantic intent based on context etc).

(STATUS : COMPLETED)

7. A query Engine : This engine will parse a query and run it on top of Modulo7 representation (STATUS : COMPLETED)

8. A persistent store mechanism : This engine will support a persistent store(database) of the vector space models for music sources

(STATUS : COMPLETED)
