Disclosed is a tuned steel hand pan tongue drum musical instrument. It is formed from joining together two thin walled steel contiguous arcuate domes. The top dome has a plurality of tuned steel drum tone fields located at various places around the periphery thereof, and a plurality of tongues cut into the steel in the upper portion of the dome. The tongues are tuned to match the fundamental frequency and/or harmonic of the different steel drum tone fields (SDTF). When struck with fingers, mallets, or other devices, the tongues emit a tuned tone and the vibration travels through the steel exciting the matched tone SDTF. The SDTF then begins resonating and produces a musical tone even though it was not touched. The reverse is also the case. When an SDTF is played, its vibration excites a similarly tuned tongue and causes it to resonate. The SDTR and the tuned tongue share the vibration and mutually benefit sonically from the effect created.
A hand pan tongue drum comprising an upper dome and a lower dome, each of said upper dome and said lower dome having a thin sheet of metal being shaped into a bowl-like configuration with an open mouth and an apex opposite said mouth, said lower dome being inverted and attached to said upper dome such that said mouth of said upper dome is contiguous with said mouth of said lower dome, said upper dome having an upper outer surface surrounding said upper dome adjacent to said apex thereof and a lower outer surface surrounding said upper dome adjacent to said mouth, said upper dome having at least one tone field situated on said lower outer surface and at least one tongue in said upper outer surface, each of said tongues in said upper dome being individually tuned to a specific tone field separate from each other of said tongues, each of said tongues being positioned in said upper outer surface of said upper dome, said lower dome having an orifice at its apex, said orifice being of sufficient size so as to enable sounds generated by tapping on said upper dome to emanate from said drum through said orifice.
A hand pan tongue drum comprising an upper dome and a lower dome, each of said upper dome and said lower dome having an apex and an open mouth, said upper dome and said lower dome being inverted relative to each other and sealed tightly together to place each of said mouths in open communication with each other, said upper dome having a plurality of tone fields in a lower outer surface thereof and a plurality of tongues in an upper outer surface thereof, each of said tongues being tuned to a specific tone field separate from each other of said tongues, said lower dome having an orifice at its apex, said orifice being of sufficient size so as to enable sounds generated by tapping on said upper dome to emanate from said drum through said orifice.
