Deirdre ventured into choral singing in 1995 when she joined the Dublin Airport Singers, and was appointed assistant musical director soon afterwards. In 2005 she decided to set up her own singing group as an experiment to see if she had any talent for conducting, and along with 15 others formed Canaigí Cantabile (later changed to Dolce). Having entered the Oireachtas and won first prize they took this as a good omen, went out and found a practice venue, looked for new members and Dolce was born.
The first few years were difficult with 20 – 25 members on the books and fewer at weekly rehearsals but they ploughed ahead. The feedback from adjudicators at competitions were always positive, and focused on the great potential of the choir. Competitions in Sligo, Kiloole, the Oireachtas, the Feis Ceoil and Cork were the aim of the choir throughout the years, and there were enough prizes won over the years to reward the members for their continuing faith.
