What does the past tense in harmony mean?

Tone is a natural tone or semitone as a transition between two chords, which makes the melody smoother.

Related introduction:

Tone is denoted by P, and two chord tones can be connected progressively by tone, which can be one or several continuous tones. Tone-through often appears in the melody part. In addition, tone-through is also often used in the bass part to form a smooth bass progression.

The bass part can also use the pass tone and the auxiliary tone. Obviously, auxiliary sounds are rarely used, because the transmission sound in the bass gives people a driving force.

Tone usually appears in weak beats or weak positions, and its duration is generally equal to or less than the chords on both sides, but not longer than them. The transmitted sound can appear in any sound, but it often appears in external sound; It can be composed of natural sounds or inflected sounds.
