20 Vocal Exercises based on the six volumes of Mikrokosmos by Béla Bartók, developed by Júlia Karosi

"My exercises are primarily designed for singers, but they can also be useful for instrumentalists as well. They develop intonation skills and connect music theory and improvisation in the context of polymodality, bitonality, modal scales, and irregular time signatures. My aim by creating this workbook was to enrich jazz with Bartók’s uniquely personal musical language, and provide new modal vocabulary for vocal and instrumental improvisation.
Without the claim to completeness, I have sampled and treated Bartók’s musical materials freely, changing melody lines, harmony, and the accompaniment. The Warmups should be practiced as scales, the Intonation Exercises as melody lines and modal scales, and finally, the 12 Improvisation Exercises, the most complex part of the workbook, prompts structured improvisations on Bartók excerpts according to specific instructions."
