Locke disclaimed competence, referring Salmon to the Compendium of Practical Musick by Christopher Simpson, and suggested John Birchensha as a teacher.
[1] Salmon gave, in July 1705, a lecture to the Royal Society on just intonation with illustrative performances by the brothers Frederick and Christian Steffkin, on viols, and Gasperini.
[1] Salmon in 1672 published an Essay to the Advancement of Musick proposing the disuse of the Guidonian hand and its nomenclature, and the substitution of the plain first seven letters of the alphabet.
Salmon also added a proposal to give up the tablature then used for the lute, and in all music to substitute for the clefs the letters B, M, T (bass, mean, treble), each stave having G on the lowest line.
Salmon in 1688 issued a work on temperament, entitled A Proposal to perform Music in Perfect and Mathematical Proportions, to which John Wallis contributed.
