Double Treble  is a project-based ensemble consisting of singers from a variety of musical backgrounds. Founded in 2011, Double Treble aims to engage with music from multiple genres and traditions in order to showcase the versatility and beautiful sonority of treble voices. Although still in its early years, Double Treble has established itself as one of Calgary's most exciting choral groups, performing everything from traditional choral classics to vocal jazz and new music. 

​

​In addition to its mandate to advance the choral art in Calgary, Double Treble is committed to giving back to the community. As such, all of Double Treble's concerts are benefit concerts, where proceeds are donated to various charities locally and abroad. In the past, Double Treble has given concerts in support of such causes as CARE Canada and the Calgary Association for the Development of Music Education.
