@@IsaacKuo , thank you. It was originally intended as a bowed lyre, but I had trouble getting a good timbre on the melody string, particularly on the high notes, without a fingerboard.

Thank you.

Thank you.

Thank you.

Thank you.

@@stephenweigel , thank you.

dude i love your stuff, i see you everywhere there is microtonal music lol

@@nomad_0036, thank you.

@@cubicinfinity2, thank you.

@@cubicinfinity , thank you.

The first. The string slips from one section of fret to another without noticeably losing volume. It can make the relationship between the pitch produced and how far you pull the string a bit odd.

@@applegarden2448 , thank you.

@@davidking9707 , thank you.

@@jdmagicmusic , thank you.

Thank you.

Thank you. I was glad to find a well known popular tune that had a distinctive riff that could be played with the notes of the harmonic series.

@@itisinickt , no.

Thank you.

Thank you. Others have made polyphonic hurdy gurdies, including this one made by Wolfgang Weichselbaumer. czcams.com/video/jNgWhgLW9zc/video.htmlsi=9J-1n_yw-yBAzJcW That's deliberately polyphonic, but some are accidentally polyphonic, for example having one string for the natural scale of the instrument and a different string for the accidentals.

Thank you.

Thank you.

Thank you. I have thought of similar designs, but wouldn't expect it to work in practice based on my experience. If they have got it to work then that's great. Thank you for letting me know about it. I will try to find out more. With sympathetic strings, the point for me is more that the strings can be tuned to very different relative intervals for different pieces of music.

The only video I have found so far that actually shows the tunefast harp being tuned shows it failing.

When I have tried similar designs and got them to work, it has been when I want to retune all the Cs in two or three octaves with just one machine head, all the Ds with another and so on. It works well with much longer sections of string and the angle that the string goes through when moving from one section to the other to not be a sharp angle. Because pitch varies as a function of tension, you can also join strings of different gauge together and change the pitch of each section by the same amount using one machine head. I haven't built an instrument on that particular principle, just demonstrated on a model that it works.

This video shows a system that allows you to speed up retuning to different scales, without having to change the tension of the strings: czcams.com/video/bvkIFgbpaIU/video.html

This uses tension retuning to tune 2 sections each of 10 strings. One section of each string is an octave above the other section. You can easily extend this principle to 3 sections of each string or 4 sections of each string. czcams.com/video/Fh_-S8qjIvg/video.html

Thank you.

Ill be watching, ​@@MabInstruments

Thank you. I haven't quite found the joy of it yet, being out of practice, but when I feel more comfortable or become less self critical, I will probably enjoy it more.

@@MabInstruments I can relate to that. I just love the gestures and expressive smeariness of slide guitar. It's fun to make other instruments more like trombones!

@@markfdesimone , I love trombone. I have been very tempted to buy one, but it might be too loud for my neighbours.

Thank you.

Thank you.

That sounds like a very intense gig. Thank you for sharing the story.

@@MabInstruments oh intense it was! Mads said he could see the exact moment the acid REALLY kicked in, i was onstage playing 'For What It's Worth' and then just WHOOSH!!! and i still had another 45 minutes to an hour of alternating music & poetry w/Mads...

Thank you. I'd need to see your design to get a better idea, but common problems are not enough rosin, too much rosin, the disk/belt not being made from a material that holds rosin well and the disk/belt being pushed too strongly or not strongly enough against the strings. Some people will also suggest that applying cotton to the strings is important, though that is not a path I have pursued myself, because every time I try applying cotton, it seems to make things worse rather than better.

If you are not using strings that are specifically intended to be bowed (for example violin strings or viola strings) then changing to strings that are specifically intended to be bowed may help.

If you are using a disk then there are questions of whether the disk meets all of the strings at the same height and what effect holding a string to the fretboard will have. My personal preference in this is to have the plane of the disk more or less parallel to the plane of the strings, having the disk behind the strings and the soundboard in front, though that is not very practical if you are trying to convert an existing ukulele. If you did follow the same pattern as me then I recommend having a raised O shaped section on the disk that engages with the strings and having an adjustment for how much each string pushes against the wheel.

This video of mine about an instrument with hurdy gurdy-like wheel and three strings of standard guitar scale length combined with a fretboard may possibly help. My impression is that it's easier to get guitar length strings to work with a wheel than ukulele length strings, but I may be wrong. czcams.com/video/DIPrd30tqQw/video.htmlsi=MKSZhnU1hzxOI1N6

@@MabInstruments Thank you so much for the generous explanation! I haven't yet bought any rosin, so I'm not able to try it on the nylon ukulele strings. Maybe rosin and cotton would work. The belt does work a little better on my steel string guitar. I will keep experimenting!

If I remember correctly the alternative was to set up the system to give painful electric shocks to one person or more people with who or where, when and for how long the shocks were administered being controlled by singing, intended as a consensual form of erotic play.

Thank you.

Thank you.

I have considered it. I'd happily make you one. Something that sometimes gets in the way of making instruments for people is the expense of sending them to different countries. I'm in the UK.

I agree, this is what I came up with as well.

I think you're right.. it's just limited to one mode of vibration, like a laser.

Thank you.

Thank you.

It's not.

Thank you.

Neither this, nor anything else, is my day job.

I have been barred from a tavern in the real world, but that was for saying things on Facebook, not singing or playing an instrument.

The tavern I'm barred from is on the same road as the bookshop with no name.
