This book compiles the scores to the scale studies of the targeted keys of F, and Bb Major, and F Minor from the Progressive Armonia Studies Level 3 book in one resource. Each major key is a collection of 115 different scale exercises and each harmonic minor key is a collection of 85 exercises for the mariachi ensemble. The score includes violin, trumpet, harp, armonía, and guitarron parts. 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. Several scale studies are in 3rd position and a few require shifting for the violin to target those skills. For the mariachi ensemble, the armonia has accompaniment in lenta, bolero, bolero ritmico, bolero ranchero, danzon, valseada, son, huapango, son variation, joropo, joropo variation, son jarocho, cumbia, cumbia variation, and polka. An optional armonía part is included in each key for students still learning how to switch from chord to chord.
