Pulse2pitch makes a continuous link between the two zones of rhythm and pitch crossing the boundary zone of shivering , laughter and rolled Rs. In this inbetween zone we experience repetitions but they are too fast to synchornise with. Zones have their favoured unit of measurement , pulse in Beats per Minute, pitch in Herz ( vibrations per second). Both units are shown across in all areas. For comparison the period in seconds is also shown. Users can enter pulse by tapping or by entering digits. Pitch can be entered numerically or by letter names.
