A Collection of 30 Etudes for Trumpet or Horn. Day-TUDES (Vol. 2) are a series of etudes that were written each day during the month of April, 2010. A group of trumpeters from around the world subscribed to the project, and subsequently received each etude daily for their own private world-premiere. These 30 etudes are in a more intermediate style, as compared to Volume 1. -the publisher
