Changing tones

In music, changing tones (also double neighboring tones and neighbor group) consists of two consecutive nonchord tones. The first moves up or down by a step from a chord tone, skips down to another non chord tone, and then resolves to the original chord tone. Changing tones appear to resemble two consecutive neighbor tones: an upper neighbor and a lower neighbor with the chord tone missing from the middle. The changing tone functions as a way to decorate or embellish a chord tone.
