This is the trumpet part of the E Major Scale Studies; a collection of 115 different scale exercises in the key of E Major for the mariachi ensemble. The collection starts in the time signature of 4/4 followed by 3/4 and ends with scales in 2/4. Scales include rhythms in whole notes, half notes, dotted half notes, quarter notes, dotted quarter notes, eighth notes, dotted eighth notes, sixteenth notes, quarter notes, eighth note triplets, and syncopated patterns in each time signature. For the mariachi ensemble, the following styles are presented; lenta, bolero, bolero ritmico, bolero ranchero, danzon, valseada, son, huapango, joropo, cumbia, and corrida. For the trumpet player, various articulations are present to work on different aspects of the mariachi trumpet style. The collection would be an excellent accompanying resource for the Rhythm and Melodic Worksheets Book 1 and 2 and the Progressive Armonia Studies book series by the same author; Carlos Maldonado.
