In music, tension is the perceived need for relaxation or release created by a listener's expectations. For example, dissonance may give way to consonance. Tension may also be produced through reiteration or gradual motion to a higher pitch (DeLone, et al. 1975, p.290).

В любом случае, это не неустойчивая ступень.

These parameters enable the i2/i3 to add to the accompaniment the tensions it detects in the chords you play. You can enable tensions separetly for each of the three accompaniment tracks. The tensions recognized by the i2/i3 are illustrated in the Recognized Chord tables in Appendix C.
