Abstract
Indicated is a method for production of a metallic-sounding musical instrument of the steelpan-type, in particular for production of a Hang®. In the method the steel sheet with a thickness of 0.75 to 1.25 mm required for the production is nitrided until the sheet is completely permeated with iron nitride needles. The linear density of the needles is, as a rule, between 40·10·103 m−1 to 80·103 m−1. The type of nitriding can be selected freely. The thus obtained instrument is characterized by novel tones.
Claims17
A method for production of a metallic-sounding musical instrument, which has a vibration-producing sheet metal membrane, in the method (a) a steel sheet blank being deep-drawn, forming a sheet metal membrane, (b) the sheet metal membrane obtained being hardened by nitriding and (c) the hardened sheet metal membrane being joined to a second piece of shaped sheet metal to form a hollow instrument body, wherein the nitriding mentioned in step (b) is carried out under conditions which result in a thorough nitriding throughout of the sheet metal membrane.
