Spontaneous A Cappella

Collaborative Vocal Improvisation


Spontaneous A Cappella is a more advanced, small-group improvisation practice, based on the Vocal River forms created by Rhiannon. We'll learn and practice ways to create vocal music together, without a score, chart or leader.

This is a deeper dive into improvisational singing, for confident singers who want to hone their improv skills.

Level One: This is a series of six 75-minute sessions where we learn and practice the basic Vocal River toolkit. The focus is one becoming familiar with the parts and forms, deep listening, blending as a group, and learning to improvise together collaboratively. 

Who should sign up… singers should be able to match pitch, hold a part, create a harmony, and blend with other singers. You should be willing to experiment, strech your comfort zone, and be willing to grow musically, through gentle feedback. 

What to expect… Every form we practice is a cappella, spontaneous, and improvisational. Forms range in participation from the entire group singing at the same time, to smaller breakouts, including duets, trios, solos, etc., both with group backing and on their own. 

What are the benefits… No matter what level singer you are, this practice will deepen your listening skills, free up your improvisational brain and voice, and strengthen your compositional skills. These exercises build skills in listening, creativity, trust, forgiveness, collaboration, generosity, and flexibility — useful tools for music and for life.
