intonation, except that the 5 and 9 draw, the main culprits in deviation from equal temperment, are tuned about 2 cents sharp of the reference pitch (rather than 29 cents flat). I also raise the reference pitch only by about 10 cents (about A=441 1/2). This puts every note on the harp within 14 cents of the reference pitch, and also within 16 cents of "concert pitch", the main "offenders" being sharp rather than flat. Chords are VERY sweet, and the jarringly flat 5 and 9 draw are avoided.
