Rhiannon competitors and assessment
Company assessmentDirect peers
- Bobby McFerrin: Bobby McFerrin is the most prominent vocal improvisation artist globally and Rhiannon's longest-running collaborator (Voicestra co-member since 1986). His Circle Singing workshops and performances are the closest direct comparison in audience, methodology, and artistic category.
- Omega Institute for Holistic Studies: Omega hosts Rhiannon's 2026 'Back to the Well' Vocal Improvisation Summit and has historically hosted Circle Singing workshops with Bobby McFerrin. Omega is a peer in the holistic arts retreat/workshop space serving overlapping audiences seeking transformational learning experiences.
- New York Vocal Coaching: New York Vocal Coaching is a private vocal training provider offering contemporary, jazz, and musical theater voice instruction with online and in-person lessons. Comparable to Rhiannon's ZOOM private lessons and advanced coaching offerings.
- Meredith Monk: Meredith Monk is a pioneering vocal artist, composer, and educator whose extended vocal technique and interdisciplinary performance work parallel Rhiannon's Vocal River methodology. Both occupy the intersection of vocal innovation, ensemble work, and master teaching.
- Hollyhock: Hollyhock is a Canadian retreat center explicitly listed on Rhiannon's workshop menu, comparable to Omega in hosting transformational arts and wellness workshops. It serves an overlapping audience of self-directed adult learners seeking intensive immersive learning.
- Complete Vocal Institute: Complete Vocal Institute (Copenhagen) is the institution that certified Rhiannon's successor Cara Trezise. CVI is a peer in the vocal pedagogy and teacher-training space, particularly for contemporary vocal technique and improvisation-adjacent skills.
Broad incumbents

While Rhiannon's niche is more specialized and improvisational, Berklee is a broad incumbent in the same customer category of serious vocal students.
