So for the second lyre I tried a much larger one. 17 strings and in the sound samples it starts with F and goes to A Key of C (tuning is not spot on for those who have a much better ear than I...). I originally tried a teak bridge but did another up from oak that seems to have a brighter sound. Frame is oak (from roadside furniture salvage and holes filled with wood filler) finished with paste wax. Front and back of the reaonator chamber is some plywood I picked up from the trash. I used acoustic guitar strings so replacement should not be a problem. Piano tuning pegs and a row of bolts to provide an attempt at "fine tuning". Nut and bridge hardware I made up from odds and ends in the scrap pile (the lower part of the bridge is a length of broken epee blade).
You can judge the sound from the samples. I was just playing a bit with the two samples and made no attempt to disguise any twangs or howling wolves. Made a lightly padded bag to keep it in -- have too many instruments that don't have any storage cases.
My overall opinion of the instrument is that it is OK but not great. Tuning is a pain and for a wood frame of this design fewer strings would work better (say 10). I do like the range of notes. Need to try thinner wood for the sound chamber. I do like the overall appearance of the lyre and was pleased with the look of the hardware.
