=== Reference pitch ===

The exact pitch frequency (typically in [[Wikipedia:Hertz|Hz]]) for the reference note, ~~based on which~~ all other notes in the scale or tuning system will be assigned a frequency, according to their intervallic relationship to the reference note. Also called the pitch reference, or tuning center, and sometimes the [[Wikipedia:Concert pitch|concert pitch]] (for an ensemble).

The exact pitch frequency (typically in [[Wikipedia:Hertz|Hz]]) for the reference note. Based on that pitch frequency, all other notes in the scale or tuning system will be assigned a frequency, according to their intervallic relationship to the reference note. Also called the pitch reference, or tuning center, and sometimes the [[Wikipedia:Concert pitch|concert pitch]] (for an ensemble).

The reference note and pitch are sometimes casually specified with a combination named note, MIDI number, and pitch frequency expression, e.g. A4-440Hz-MIDI.69, meaning 440 Hz exactly for the A above middle C, because A4=440Hz is the international standard. For cases other than A4=440Hz, in a tuning specifier like C4-261Hz-MIDI.60 for example, the "261" is typically an approximation. It implies a more accurate number should be specified in the tuning file itself, with 2-4 digits after a decimal point (e.g. 261.6256).

=== Linear keyboard mapping ===

A mapping between scale and keyboard controller keys, ~~such that~~ the notes of the scale are simply applied in a sequential order starting from the tuning base. In the absence of an explicit keyboard mapping, music software will typically assign linear keyboard mapping. ~~Consequently,~~ the pattern of black and white keys on a standard piano keyboard might not align with meaningful intervals of the scale.
