From: christopherv (2011-02-23) Subject: Autoharp Zither - microtuning to a set of chords? I was lucky enough to pick up an 12 chord Autoharp Zither for $42 (including shipping) from Ebay (new these are > $200). Picture, example song, and 12 edo tuning information (jpegs)are here: http://notonlymusic.com/board/viewtopic.php?f=11&t=803&start=0 Now, of course I'd like to microtune this baby. However, this poses an interesting challenge because of how it works. One is suppose to / can strum the entire width of the autoharp and chords are formed by pressing felt dampers onto the strings to silence the unwanted notes. So... the A notes get used in A7, Dm, Am, D7 and need a working relationship with the other members of those chords. So, while I'm used to the idea of taking a tuning and finding a set of chords from it I wonder if anyone here has done the reverse - that is taken a set of desires chords and worked out a non-12 edo tuning that makes them all usable. The 12 chords of my autoharp zither are: Gm, Bb, A7, C7, Dm, F, E7, G7, Am, C, D7, G

I could do that for you if you like, or you could use your favorite meantone.

Gene, I'd be very appreciative if you'd come up with something for me. - Yes, dominant 7ths in this. Do you think it possible to do implement a more exotic tuning and have the chords sort of work out as well?

So we are talking about a gamut of 11 notes of meantone.

It might be. Can the order of notes be changed in the tuning?
From: Chris Vaisvil (2011-02-24) Subject: Re: [tuning] Re: Autoharp Zither - microtuning to a set of chords? Thank you very much!! I will give this tuning a try - though the zither is full chromatic (12) so I'm not sure which note I should double up here - but I bet I can find out with some experimentation. The note order in the zither can be changed to a degree easily by changing the tuning - if the difference isn't too large (I'd say a up to 200 cents, may be 300 cents) On Wed, Feb 23, 2011 at 6:49 PM, genewardsmith <genewardsmith@...>wrote: > > > > > > Here you go: > > ! chris.scl > 11-note 5-limit meantone lesfip > 11 > ! > 71.99829 > 191.39229 > 384.18843 > 503.58243 > 575.58072 > 695.11120 > 769.76122 > 887.79036 > 1005.81950 > 1080.46952 > 1200.00000 > > > > Do you think it possible to do implement a more exotic tuning and have > the > > chords sort of work out as well? > > It might be.

I doubled up the 384 cent note (I think or the one below it). http://micro.soonlabel.com/autoharp-tunings/STE-000-zither-tune-11-note-5-limit-MT-lesfip.mp3 I think some of the chords are really beautiful. this has a lot of potential!

It's missing Eb; Eb could be 307.71749 to fit in with the rest.

Hi Gene, I gotta stop tonight (Daughter is sleeping) but I'll put that on the list for tomorrow. I really like how it sounds!!
