Impromptu red wine.jpg

In 2008, a group of women, bound by their love of music and musical performance, came together to form a community choir that welcomes all women who desire music in their lives.  We meet Sunday afternoons to practice our songs, to share our talents, and to enjoy each other’s company.


Impromptu performs once a year, each spring, a program of uplifting music that reflects who we are, strong women who live life fully.  We have also “taken our show on the road” to Santa Fe, New Mexico, Portland, Oregon, Georgetown, Colorado, and Colorado’s Western Slope.  We are proud to have also participated in fundraising concerts for SafeHouse Denver for women in need of support.


Our symbol of a treble clef surrounding a glass of wine reflects the joy we find in singing and gathering together.  As important as music is to us, the social time we enjoy after rehearsals also brings us together as we share our daily lives, our hopes, our dreams, our joys and sorrows.


Impromptu is a unique musical community made of women from all walks of life: doctors, nurses, lawyers, professional musicians, travel agents, homemakers  . . .  If you love music, there is a place for you in Impromptu!

Eric  Britton, Accompanist

Eric has enjoyed music and playing piano and trombone since the age of seven. Highlights have included summers spent in the asthma-inducing pine forests of northern Maine at the New England Music Camp, soloing in a national competition with his high school jazz ensemble at the Berklee College of Music, and deciding to take up accompanying in college when he realized his future wife was sitting in the alto section of the Dartmouth Chamber Singers....and he needed a way to meet her.

Eric loves the weekly invasion of his living room by the wonderful “Ladies of Impromptu”, and truly appreciates their passion and enthusiasm for making music. He never realized, however, that there was so much to catch up on and chat about during rehearsals.


Other passions include hand surgery, squash, and chasing a little white ball through the fields and fairways.
