Editing Dulzaina (section)

===Registers===

The dolsaina's effective range is divided into two registers, middle register and upper register. They can be distinguished by their timbre and by the way they are produced.

1. '''Middle register:''' The sound is natural. It is the most relaxed register. It comprises the first octave, from low D (concert A 3) to high D (concert A 4). Tuning in this register is relatively easy.

2. '''Upper register: ''' they are the first harmonics of the natural notes. They can be produced by increasing the air pressure - commonly known as "over blowing". Tuning in this register is very hard and playing the notes in it is tiring and difficult. Sustaining playing in this register is truly exhausting. It is situated in the second octave, from high E (concert B4) to high A (concert E5).
