Personal Pianist is the product of years of teaching experience and experimenting by two professional musicians, one a violinist, and the other a cellist. The program is a very simple, easy-to-use practicing tool for students and parents, with which you can rehearse many pieces of music with a piano accompaniment. Several main features of the software and available piano libraries are:  1)  The ability to change tempo, to allow students to find a speed which they can handle, and gradually increase the tempo as they improve, and; 2)  The inclusion of "rubato" or musical feeling . . .
