Musical instrument builders not only build musical instruments, but also restore, repair, alter or adjust them, by using special techniques such as wood carving, silver smithing and cabinet making. They make and design instruments and their parts.
Musical instrument builders make and assemble instrument parts, tune instruments, attach strings and install electrical wiring for instruments. They also tell their clients about the instrument and its acoustic properties.
Musical instrument builders need to know exactly what people are looking for. Most musical instrument builders specialise in one instrument, but some specialise in various instruments, usually from the same group, eg. electronic, wind, string or brass.
