István Szelényi (1904-1972), a student of Kodály, taught composition at the Budapest conservatory. Apart from chamber music and piano pieces he composed mainly educational material, e.g. for youth orchestra and violin ensemble. Improvisation, composed 1946, is equally suited for violin, flute or oboe. Simple piano chords provide the background for a rhapsodic, improvisatory solo part with an eastern European folkloristic flavour.
