Preferably the strap is secured at one end to one end of the bar member and the other end of the bar member has a transverse slot therein through which the other end of the strap can be passed and doubled back on itself and secured by means of a releasable touch-and-close fastener the two components of which are provided at different positions on one surface of the strap. In an embodiment at least one tuning reed is provided in a bore in the bar member to enable the capo to serve the further function of a pitch-pipe for tuning.
