This is the armonia part/accompaniment to 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. The armonia has accompaniment in lenta, bolero, bolero ritmico, bolero ranchero, danzon, valseada, son, huapango, joropo, y corrida. An optional armonía part is included for the students who are still learning how to switch from chord to chord. 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.
