Abstract

Music performance (for example piano concert or symphony orchestra) requires turning music sheets during concert. Such action is very distractive for performer and audience. In some cases another artist help is required to do it properly. This article presents automatic music sheet turner based on Independent Component Analysis method.

Adopton of ICA method for sheet music turner in synch with orchestra performance

Music performance (for example piano concert or symphony orchestra) requires turning music sheets during concert. Such action is very distractive for performer and audience. In some cases another artist help is required to do it properly. Thanks to adoption of Independent Component Analysis method we are able to differentiate/split mixed signal into independent signals generated by particular musician. Independent Component

Analysis - is a computational method for separating a multivariate signal into additive subcomponents. ICA is a special case of blind source separation. A common example application is the "cocktail party problem" of listening in on one person's speech in a noisy room. In our case the coctail-party problem is multi-musician problem which can be solved in the same way. There is also one more advantage of such application - at the end it is possible to analyze/listen to each musician separately (training purposes).


1. Each music instrument synch up with corresponding electronic device
2. All devices are connected into one network (data sharing)

3. Sound analysis is being performed with ICA algorithm (or any other signal separating method) and page turn action is predicted per each device / instrument
4. In case of latency problem we can always assume comfort margin to add (display more)

There are applications designed for solo performance (e.g single piano) analysis...
