This is the harp part to a collection of 85 different scale exercises utilizing the C 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. 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. The harpist will practice scales, alternating left and right-hand parts and chords to the different rhythms. 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.
