On the summits (Sur les cimes) by Eugene Bozza (1905-1991) is a very enjoyable piece for F Horn and Piano which lasts 7 minutes. Difficult to play, it requires the mastering of techniques such as the glissando, the lip trill andthe mute. Also challenging because of its cadenza part, it was composed in one movement which features five sections. Eugene Bozza won different prizes at the Conservatoire de Paris such as the First Prizes for the Violin,conducting and composition, as well as the Grand Prix de Rome. He composed several operas, chamber works and ballets among others.
