Cathedral Treble Choir

Marianna Parnas-Simpson, Director

The Treble Choir of Houston at Christ Church Cathedral was founded in 2006 by Marianna Parnas-Simpson, and has flourished and grown artistically since then. This diverse choral ensemble of children ages 11–16 performs widely in the community and also serves as the resident children’s choir at Christ Church Cathedral.

The Treble Choir is composed of children from the Cathedral and greater Houston community and rehearses on Tuesday evenings from 5:00–6:30 p.m. In addition to singing at the Cathedral for Eucharists, Evensongs, and other special events, the Treble Choir often serves as a guest children’s choir for concerts and weddings.

  • Self expression and self confidence
  • Better understanding of the world, the people and ourselves

Treble Choir of Houston performance of the Russian song “Prekrasnaya Dalyoko” brought tears to my eyes. I grew up in Russia and this was one of my favorite songs. The pronunciation was so clear — you could never tell that those children are not native Russian speakers. It was the best performance of this song I have ever heard.

I was blown away by the beauty of the Treble Choir performance in Carnegie Hall. The sound of these young singers was clear, warm and beautiful. Children’s faces were lit up with inspirations — they were a joy to watch and hear. I left uplifted. Thank you for the gift of music!
