My shepherd pipe is a student version of my Flemish and border pipes G. I have minimised the cost by giving it a single drone and simple decoration.
The chanter has the same octave and a half range and chromatic notes and the drone is bass G. The reeds are plastic and stable.
I go to a lot of trouble to get the chanter dead in tune against the drones. Well-tuned pipes are much easier to play than slightly out of tune pipes. This is because the player is not trying to adjust the pitch of each note by changing bag pressure, consciously or unconsciously. This also improves drone stability and register shift up and down the octave.
I use the traditional half closed system of fingering which is the best system for gracing. On the G instrument cross-fingerings give the accidentals Bb, C#, Eb, F#, G# and top Bb.
I fit a black gortex lined calf skin bag as standard. They remain airtight and never need dressing/seasoning.
Available in damson or bubinga wood.
