The Orchestra Tax Relief (OTR) is offered to instrumentalist groups on public musical performances. I think the human voice is a versatile instrument capable of conveying emotion, rhythm, melody and harmony yet doesn't apply as a qualifying instrument for OTR, and this unfair definition must change.

A cappella choirs can face the same financial challenges as traditional orchestras do in putting on paid public performances but are disqualified from claiming OTR because of Treasury rules. The opportunity to sing in public performances can promote mental wellbeing whilst also funding the choir's progress, so where is the commonsense in excluding a cappella groups from the ability to claim OTR ?
