A couple of clips of the scale played on the highland bagpipes with the low G substituted for another note. Low A is tuned to 480 Hz + ~10 cents.
Low F# – obtained by taping over one tone hole entirely and taping over the other a little bit for tuning. Grace notes to and from low F# sound and act fairly normal.
Low E – obtained by taping over both tone holes entirely and extending the length of the chanter just a little bit with a ring of tape on the very bottom, less than a centimeter in length. All the grace notes on the bottom hand work well enough, though throws and such don’t work very well. All the top hand grace notes produce a squeal.
