The first person who can correctly tell me 'what', and/or 'why', gets a free hug.
Second prize is two hugs.

If you can guess what's going to follow, I'll give you a cookie. :)

Luthiers, flame me at will.

Bit big for a violin, and definitely not standard in several respects, but electric is getting close.

3.5" floppy for scale. ^^

Cello is right (medium four-stringed instrument), and the frets are probably a surprise, but no mistake wink
**hugs Steve** You've got Aussie germs now. tongue



Now, for second prize, have a think about the second pic / the bridge.

From whom??? Do I get to choose? wink

What I notice (in addition to the addition of frets) is the bridge is flat (so the strings are all in one plane), which tells me it's for strumming like a guitar, as opposed to being in the traditional curve so that one or two strings (but no more) can be played with a bow at one time. I supposes you could also play all four of these strings with a bow.

Eclectic?

Okay... I don't see a magnetic pickup, perhaps there's a piezoelectric pickup between the bridge and body?

I was thinking that maybe its catering more to students learning the instrument, but doesn't make much sense because transitioning from fretted to fretless would be half a step low. I'm thinking that students would place markers on the fretboard insted of learning on a fretted instrument.

So what I'm thinking now is that it is fretted so the musician can make chords. This is pretty trivial on guitar most of the time. I've played bass making some power chords, which is tough for a guitarist, but possible.

So I'm going with the notion that its fretted to make chords.

I'd like to see the musican do some tapping on the chello...now that would be a sight.

Nope, sucks to be you! **hughug** =-P

Very well noted about the modified bridge -- the string profile is altered so that the strings are very nearly coplanar, leaving enough margin that an apt player may bow any combination of #1, #1+2, #1+2+3, #1+2+3+4, #2+3, #2+3+4, #3+4, #4, at the expense of the two middle strings being tentatively impossible to play individually.

Strumming four strings like a guitar is very straightforward on a 'cello without any modification; the mod was to affect the bowing behaviour. The sound from four stopped strings resonating from one instrument is quite confronting and a bit ethereal... probably because one doesn't expect it! Think of "Masked ball" from the soundtrack of "Eyes wide shut".

Eclectic is right, too. ^^

The electric bit will involve a pickup under #1+2, and another under #3+4 going to a PC sound card (stereo) and some software I'm writing in C++ will allow realtime alteration of the sound... then if I ever finish my testing and framework, I'd put some strings and a bridge onto something that won't resonate, so the only sound comes from the computer, and the (by then hardly a) 'cello' will be silent itself.

Hazmatt is correct about the frets. **cookie**
I deliberately took the photo to only include the top end of the fingerboard; the five frets you see there are the only frets on the instrument, meaning that as soon as you hit third-and-a-halfth or fourth position, you're off the frets, making possible again glissando and vibrato and proper solo playing.

The modifications make this cello harder to play rather than easier, and I love it! wink

I'll give it a try for you when I attach my new-and-improved frets. =)
