It is a method used widely by teachers to teach their students to improve in their performances. This method is divided into three different studies which are Eurhythmics, Solfege and Improvisation. Not only does it improve performances, but the understanding of music becomes deeper thus understanding the piece you are playing in terms of form structure, analysis and so on. These methods can be fun and also its a good way of exercising. Now that's what I call killing two birds with one stone.
There are a few exercises in this website for you to try out. Invite your teacher and friends along to join in this learning and fun activities!
