Sonatina for Violin and Piano, Op. posth. 137, No. 1, in D Major, D.384; Franz Schubert
Every CD opens with a full concert performance, followed by keyboard accompaniments at slow, and then medium tempo, for practice purposes, with the solo instrument heard softly as a guide.
In the final track, you are the soloist, accompanied by the orchestra, piano, or basso continuo at the original tempo. Every CD has been recorded live, by distinguished soloists, accompanists and orchestras.
