This project is derived from a musical composition, a modern "classical" string quintett.

The program's aim is

• to calculate all possible permutations of up to 11-note chords based on a given interval order;
• store the results in a database;
• render the results (preferably in LilyPond format);
• provide the user with a UI for selecting material for her/his own compositions and query the database.

The following amount of chords is calculated (ordered by number of notes per chord):

Technical overview

The program is written in Java (6), using a "classical" Spring Framework architecture (Services and DAOs). MySQL is currently supported as DBMS. The execution of the program takes currently 2 days on an average computer storing the 68.586.311 chords needs a disk space of ~35 GByte.
