This is the armonía part to a collection of 85 different scale exercises utilizing the G harmonic minor scale 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. The collection would be an excellent accompanying resource for the Rhythm and Melodic Worksheets Books 1 and 2 and the Progressive Armonia Studies book series by the same author; Carlos Maldonado.
