from lat. second – second
1) The interval formed by the adjacent steps of the musical scale; denoted by the number 2. They differ: a major second (b. 2), containing 1 tone, a small second (m. 2) – 1/2 tones, incremental second (amp. 2) – 11/2 tones, diminished second (d. 2) – 0 tones (enharmonic equal to pure prime). The second belongs to the number of simple intervals: minor and major seconds are diatonic intervals formed by the steps of the diatonic scale (mode), and turn into major and minor sevenths, respectively; diminished and augmented seconds are chromatic intervals.
2) Harmonic double sound, formed by the sounds of neighboring steps of the musical scale.
3) The second step of the diatonic scale.
