Baritone tuned 6 string guitar - BEADF#B

The standard method used when baritone tuning a six-string guitar such as the CF Martin Grand J-28 LSE involves tuning all the strings a perfect fourth lower than normal, i.e. B E A D F# B.

If the C major scale is mapped over the fingerboard using this standard baritone tuning (with all of the C naturals highlighted) it produces the following:-

Using this baritone tuning the C naturals are no longer where they are expected to be found; however if the
G naturals are highlighted instead, the normal C natural octaves pattern appears, as shown in the image that follows:-

GuitarPro6 baritone G naturals

When this standard baritone tuning is adopted the player pretends that the G naturals are in fact sounding as C naturals; in the same manner adopted when a capo is used. The instrument has then been turned into a transposing instrument rather like a saxophone or clarinet; where the note being read (or thought about) is not the one sounding.

This is NOT the tuning being explained below; instead the information presented is offered as a gateway tuning to a 7-string guitar rather than another way to get different sounds out of the same guitar patterns.

So you want to learn how to play 7-string guitar but you don't have enough readies to go and buy one.

Well fear not boys and girls because Zon Brookes always has a work-around solution under these types of circumstances.

Get yourself an old 6-string electric guitar with a Strat scale length i.e. 25½" and a new set of 13 gauge strings.

The C major scale is shown below on the GuitarPro6 fingerboard for 7-string guitar with a low B string:-

A standard 6-string electric guitar represents strings 1 to 6 of the previous 7-string; as shown in the next GuitarPro6 fingerboard:-

Instead of tuning your 6-string EADGBE why not tune it BEADGB which represents strings 2 to 7 of the previous 7 string?

The C major scale is shown below on the GuitarPro6 fingerboard for a 6-string guitar tuned BEADGB:-

Won't a 25½" scale length be too short?.... I hear the purveyor's of all guitar wisdom cry from afar.

Well follow this link to check out the specifications of the Ibanez UV777 to quell any fears you may have on this front - scale length of 25½" I do believe.

Again the guitar-wise are shouting the strings will be too slack.

This is where the 13 gauge strings come in useful and if you want to do a full string tension calculation check then follow this link to the D'Addario strings design chart (very useful for this precise purpose).

So to quote those of an American persuasion y'all set.

This issue demonstrates the A minor-diminished arpeggio box shapes for 6-string guitar tuned to BEADGB with the all important orange letters omitted.

The CAGED octaves sequence is shown for A natural in the diagram that follows:-

The diagrams that follow show all of the A minor-diminished arpeggio notes plotted over the 6-string guitar's fretboard (tuned to BEADGB) in the CAGED octaves styles:-

As always a more long term solution to fretboard navigation is to see scales/arpeggios as INTERVAL shapes rather than note names - as these are universal to all scales, arpeggios and chords rather than specific to one particular root note - with this in mind the intervals for the A minor-diminished arpeggio are detailed below in the CAGED octaves manner:-

The table and tabbed panel below details all five box shapes for the A minor-diminished arpeggio in the
CAGED octaves style.

Once the individual box shapes have been assimilated all five shapes should be linked together and played in one continuous exercise (with the first shape - 4Am2 - being repeated at the 12th fret).

The video shown to the right demonstrates the CAGED octaves chain-linked sequence for the A minor-diminished arpeggio box shapes.
