11.- Separation or Repetition of Equal Notes in the Pipes.
There are two ways to separate two notes of the same tone:
a) Gracenote.This consists in making a quick dry strike with one or more fingers at the same time, normaly higher than the note that we are repeating.
b) Strike. This consists in striking with one or more fingers simultaneously, over the open holes of the "Punteiro".
Graphic Representation of the Gracenotes and Strikes.
They will be represented in writing by notes which are smaller than the main notes normally in "fusas" with the "plicas" facing down. These small notes don't have assigned value, because they only represent the movement of the fingers; Taking there value from the previous note, not the following.
There are certain contexts in which it is neccesary to write down the note that result from these finger movements, such is the case in the D strike in the second octave, that we represent with a D of the first octave, resulting from striking with the fore finger of the left hand.
The alterations will only affect the principal notes, so they should always be situated in front of the principal note, not before the gracenotes or ornaments.
The gracenotes and strikes can be used to separate equal notes or to emphasise notes with a distinct tone, achieving, in the case of the gracenotes, the character staccato.
When we have to make several consecutive gracenotes, especially in quick notes, they should be done, by alternating distinct fingers, this means that we achieve sharp gracenotes, and clean sounds, of exagerated harmonics derived from the consecutive repetition of the same finger; This will require a lot of concentration at first, so it is very important to follow the exercises to achieve this goal.
For the interpretation of the gracenotes or strikes only the fingers which are represented should be moved. All the notes, as much the altered notes as those in second octave, can be separated by using strikes except the C sustained of the first octave, that can only be repeated by a combination of gracenotes. All the notes can be repeated using the gracenote system.
Combination of gracenote strike.
The combination of the gracenote strike is one of the most traditional techniques for the separation of notes of the same pitch in the galician pipes. From the point of view of the variation of each technique, it seems advisable to make coincide the strong part of the tempo with the gracenote.
We recognise that we shouldn't establish a fixed rule, for the separation of the notes of the same tone in the Galician pipes, because the finger or fingers used, in each context can vary according to the tonality of the "punteiro", the construction of the "punteiro", apeture of the reed etc. For very high-pitched tones strikes should be given the priority.
Although according to the experts there are many ways to separate equal notes in the pipes, all them are valid, and reflect different styles; These days the Galician pipes is being seriously studied, and so careless gracenotes, normally, too slow and repetitvely played by the same finger, although the notes may be rapid, they don't favour, either the purity of the sound, or the speed of the interperatation. Because of this, our concern is to get used to using the gracenotes with strikes, and the gracenotes amongst themselves, properly.
