A combination cymbal fastener and drum-tuning key forms a T-shaped tool (14) having a handle (30) connected to a shaft (32). The shaft (32) has an internal cavity (40), circular in cross section, which is threaded (38) for attaching the tool (14) to a threaded rod (44) of a cymbal stand (6). Ultimately, the internal cavity (40) penetrates the end of the shaft (32) nearest to the handle (30), creating an entrance hole (42) by which the threaded rod (44) of a cymbal stand (6) may enter the tool (14). At the tip of shaft (32) located opposite the handle (30), the shaft (32) contains a tuning socket (34). The tuning socket (34) is square in cross section and fitted to slidably mate with a drum's tuning screw (22). Alternative embodiments are also described.
