We take a look at a model of computer aided generation of Hindustani Classical music.
The system implemented using the model is essentially a simulation of the ‘Arohana’
and ‘Avarohana’ of a particular ‘Raga’. The artificial generator creates note sequences
using hand-crafted bigram finite state models which conform to the grammar of a Raga.
We also describe a procedure that intends to measure the quality of the artificially
generated compositions by comparing them with random sequences which have been
generated from unigram models. The measure makes it evident that the computer
generated sequences are better than the random ones. However, the compositions are
nowhere near the quality of human created ones and therefore this leaves a lot of scope
of further research in similar areas.
