stringcalc.tension.suggest_gauge(T, L, pitch, *, types=None, n=3)#

For target tension, given scale length, and pitch, return suggested gauge(s).

Two types are commonly used to make string sets, e.g. plain steel + phosphor bronze for steel-string acoustic guitar or plain nylon + silver-wrapped nylon for classical guitar.

Parameters:

  • T (float) – Tension [lbf].

  • L (float) – Scale length [in].

  • pitch (str) – Pitch name in ASCII SPN, e.g. “A4” (A440), which is a fourth above the guitar’s high E string. Guitar standard tuning: E2 A2 D3 G3 B3 E4.

  • types (set[str] | None) – String type IDs (column group_id in the data table) to consider. If unset, defaults to D’Addario phosphor bronze and plain steel ({'DA:PB', 'DA:PL'}).

  • n (int) – Number of suggestions to include in the returned frame.

Return type:
