5.- Transposable and non Transposable Pipes. Tunning tone
Transposable and non Transposable Pipes
The bagpipe family, like other families of wind instruments, are made in diverse types, with the essential difference being the size of the pipes. Because of this difference, the same "burato", "ronco", "ronqueta", or "chillon", can produce in each type of pipe a different tone.
Conveniently for practical reasons, we have kept the same name of note for each "burato" of the "punteiro", even if they have distinct tones.
From the previous argument we can conclude that only the pipes in D can be considered non transposable, because the sound given to the notes is the actual note that is re-produced.
As for the rest of the tonal classes of pipes, we can call them transposable, because the sound produced is not the same as the actual corresponding note.
Tuning Tone of the Pipes.
It is corresponding to the note, that is actually emmited, when we play what we call the D on the pipes; Therefore if the resulting note or sound produced is in C, we say that the pipes are tuned in C (in these cases we use the piano as a reference); If the resulting sound is a B flat on a piano we understand that the pipes are tuned in B flat etc.
