View Full Version : Guitar as a Electric Mandocello?

Let me preface this a bit.

Way back when I was a child I played the Cello for a few years, I was never all that great, but I got just enough of an understanding to forget most of it by now. I've been playing guitar for quite a while, and I'd become interested in various different tunings. One that struck me was called "New Standard Tuning" which, like the Mandolin family, was mainly tuned in fifths. I rather enjoyed playing with it, but there was so little material and support that I didn't see myself having an easy time continuing. I later ran across some various videos of mandocello music, and I was amazed.

Long story short, I want to tune a Guitar like a mandocello, and I'd like some input. Any wisdom you can share, or input you may have would be greatly appreciated, especially if I made a mistake.

My thought is to have a string a fifth higher and a fifth lower bringing my tuning to E4, A3, D3, G2, C2, F1. In order to play properly, at a 25.5" scale length, I need the following unit weights for each string to keep the same tension. (I've also included the D'addario string ID numbers that I plan to use)



E4 - 0.0000221492 lb/in - PL010 (Standard High E String)
A3 - 0.0000472685 lb/in - PL015
D3 - 0.000110941 lb/in - NW026
G2 - 0.000284624 lb/in - NW039
C2 - 0.000677188 lb/in - NW060
F1 - 0.00136423 lb/in - XLB085**Because there aren't many Guitar strings thick enough to hit the low F, I went with a bass string. Since I was looking for Unit Weight based on my own calculations, rather than using a chart of some sort, it will create the intended sound on a guitar body.

Because the strings are thicker than the standard set, I will have file the nut a bit. I may even need to either take a drill to my tuning pegs, or get a few bass pegs.

The low F is only one note short of the lowest note on a standard 4 string bass guitar, a bass amplifier would be required for consistent volume across the range of the instrument.

As far as education goes I am considering ordering the Chord Genius book on mandocello (http://www.northernmusician.com/), but I would like a method book to accompany it. Any recommendations, and/or opinions on the Chord Genius book, would be greatly appreciated.

Random,
I'm not sure what you want to know. But I've got comments anyway. :)

I've tuned an electric as a mandocello with six strings like this (low to high:) CGDAEG. That last G is up a third from the e. A "B" would have been impossible.

This tuning required reintonation of the saddles. I wouldn't want to go any lower that C for the reasons you suggest, refiling the nut and using a different amp that's not really designed to handle electric guitar. Also I'm not sure that F will intonate properly.

For CGDAEG tuning look into Robert Fripp's League of Crafty Guitarists. He tried to set up this tuning as "New Standard" and started a summer workshop in West Virginia. I don't know if he's still doing it. However, 5ths tuning is the same no matter which instrument or notes you're using. So the tab to a song will work in any tuning, though the key will change according to the tuning. But that just means you'll learn to transpose faster. ;)

Hope this helps,
Daniel

Hello, and this being your first post, Welcome!

And not having been around these parts, you couldn't know that we do tune like you describe. :) I did some experiments with the low F (http://www.mandolincafe.com/forum/showthread.php?t=27680&highlight=teleberger), but was not crazy about it after a while. The NST was next, but that goofy G on top always prevented me from buying in 100%. Then a guy on this board (and others) introduced us to the Octave4Plus line of strings, and we all happily tune our guitars CGDAEB. They do make strings to go that high. (B4)

I call it a jazzCittern, but it ain't nothin' but a big mandolin, so it sure would be appropriate to call it an electric mandocello. Our 'social group' is here on this board (http://www.mandolincafe.com/forum/group.php?do=discuss&group=&discussionid=283), in case you want to stop in.

I'll bet T.J. weighs in real soon.

Luthier Fred Carlson made an instrument he calls the Harpeggione (http://www.beyondthetrees.com/hartext.html). He discusses his experimentation with tunings etc. at that link.

Harpeggione takes off on the Arpeggione which was a 19th century variant of a fretted cello tuned like a a guitar. I know that is the opposite of what you are trying to do.

This thread, (http://www.mandolincafe.com/forum/showthread.php?t=45977) too. John McGann shows his NST axe, and we all talk fifths.
