A 3 CD set with almost four hours of material that teaches good singing technique and how to stylize, using eleven standards played by a jazz trio. The Vocal Warm Up Section includes the songs with vocals and instructional tracks. The Vocal Style Section includes the songs with more stylized vocals and instructional tracks. CD #3 has the same songs minus the vocals so singers can work 'without the training wheels.' These tracks without vocals can be used as a vocal warm up, or for practicing different vocal style concepts. The Vocal Warm Up and Vocal Style sections can be used independently of each other. The songs progress from very easy to fairly difficult. Low to high alto range: Eb- Eb (two octaves)
