tuning

Tuning is the practice of adjusting instruments or voices to correct pitch. Remove the concept of pitch and tuning has no target — it ceases to operate. Per Law 8 removal test: X needs Y operating now. Tuning NEEDS pitch to function as a concept.

Tuning is the practice of adjusting an instrument or voice to match a reference pitch. Remove the concept of reference and tuning has nothing to adjust to — no standard, no target, no operation. The dependency passes the removal test: without a reference concept, tuning cannot function. Direction tested: tuning exists because references exist (references came first conceptually).

Tuning is the process of adjusting pitch to match a target frequency. Remove frequency and tuning has no operational framework — there is no concept of pitch matching or deviation to work with. The removal test passes.

Law 9 specific to nearest accepted kind; Law 11d pinned senses against both accepted defs. tuning's accepted definition carves the practice/framework of standardized pitch relationships and names its second parameter 'temperament — the system of interval sizes (equal, just, meantone)' — equal temperament is precisely the 'equal' case of that parameter, the interval-size system that tuning's framework holds. A competent speaker calls equal temperament 'a tuning system' (the literature defines temperament as a system of musical tuning). No nearer accepted kind exists on the board (the word 'temperament' is unheld, so no intermediate rung). Pinned senses: equal-temperament as the 12-equal-step interval-size system; tuning as the framework that includes interval-size systems as its temperaments.

Pitch estimation is built for the sake of tuning — pitch estimators are designed to determine pitch for tuning purposes (musical instrument tuning, voice training, auto-tune systems). The pitch estimator serves the tuning function.
