Speed is simply referred to as the distance that is traveled by someone or a particular thing per unit of time. Speed has to do with how fast a particular object can be.
Speed is considered to be a scalar quantity and its s.i unit is then meters per second.
Its unique interval is that between 6-7 -- the whole plus half step (or augmented 2nd). It can be thought of as a natural minor scale with a raised 7 scale degree.
