The presence of the described resonance device in the form of resonators (3, 4) influences the vibration characteristics of a membrane (2) in a defining manner and ensures a harmonic relationship between the fundamental and overtones of the drum sound, even if said drum does not have a closed sound box or shell (1). In orchestras and ensembles, but also as a solo instrument, the acoustic presence is improved by the increased energy conversion efficiency of the instrument and by the increased precision of the overtone characteristics with the aid of the ring resonators (3,4). The resonance device therefore enables the drum to be precisely tuned to a fundamental pitch in a given harmonic musical concept.
