Editing Plectrum (section)

===Voicing harpsichord plectra===
The plectra of a harpsichord must be cut precisely, in a process called "voicing". A properly voiced plectrum will pluck the string in a way that produces a good musical tone and matches well in loudness with all of the other strings. The underside of the plectrum must be appropriately slanted and entirely smooth, so that the jack will not "hang" (get caught on the string) when, after sounding a note, it is moved back down below the level of the string.

Normally, voicing is carried out by inserting the plectrum into the jack, then placing the jack on a small wooden voicing block, so that the top of the plectrum sits flush with the block. The plectrum is then cut and thinned on the underside with a small, very sharp knife, such as an [[X-Acto|X-Acto knife]].<ref>Kottick (1987)</ref> As the plectrum is progressively trimmed, its jack is replaced in the instrument at intervals to test the result for loudness, tone quality, and the possibility of hanging.

Voicing is a refined skill, carried out fluently by professional builders, but one that usually must also be learned (at least to some degree) by harpsichord owners.<ref>Source for all of this section: Kottick (1987)</ref>
