G-G-D-G-B-D • OVERVIEW • Like ‘normal’ Open G, but with 6str tuned to G rather than D – either upwards or downwards. This takes the open harmony into ‘uninverted’ territory (i.e. the open Gmaj chord now has a G in the bass). Whether set as octaves or unisons, the adjacent Gs (6+5str) beef up the […]

• Banjo (‘Overtones’) tuning •
 


• Open G (‘Taro Patch’) tuning •
D-G-D-G-B-D • OVERVIEW • Resembles a Standard-tuned Amaj shape in terms of interval structure (‘0-0-2-2-2-0’). Gives a more ambiguous resonance than the other ‘main’ maj-chord tuning – Open D – as its major triad is arranged in ‘inverted’ fashion, with the 5th (D) in the bass rather than the G root (which is on 5str). […]
 


• Open Dsus (‘DADGAD’) tuning •
D-A-D-G-A-D • OVERVIEW • Resembles a Standard-tuned ‘0-2-2-2-0-0’ Esus4 shape in terms of interval structure. Neither major nor minor, DADGAD’s ambiguous open-chord resonance offers up incredible versatility, ideal for exploring the musical variety of many global traditions. Regardless of what you play, there’s always a certain fundamental stability to the tuning’s character, partly arising from […]
 


• Open Dm (‘Bentonia’) tuning •
D-A-D-F-A-D • OVERVIEW • Matches a Standard-tuned Emin shape (‘0-2-2-0-0-0’) in terms of interval structure – with everything twisted a whole tone lower. Thus forms a ‘cross-note‘ layout, as (unlike in Open Dmaj) you can easily ‘cross over’ to major voicings with just one finger (e.g. ‘0-0-0-1-0-0’). Associated with haunting Delta bluesman Skip James (and […]
 


• Open D (‘Vestapol’) tuning •
D-A-D-F#-A-D • OVERVIEW • Resembles EADGBE’s famous ‘0-2-2-1-0-0’ Emaj shape in terms of intervals – a general pattern sometimes known as ‘Vestapol’ (after The Siege of Sevastopol, an earnest 1854 American folk song about the Crimean War, popular in parlor guitar instructional manuals of the 19th century: more below). Thus, the tuning represents a logical […]
 


• AirTap! tuning •
F-A-C-F-C-F • OVERVIEW • Used by Montreal acoustic genius Erik Mongrain to facilitate the virtuosic ‘lap-tapping’ techniques of AirTap!, an oldskool viral favourite (uploaded way back in 2006: YouTube’s early days). Like playing piano, bass, & drums on the strings – all at the same time… The interval structure matches our ‘classic’ Gmaj shape […]
 


• Square-Neck Dobro tuning •
G-B-D-G-B-D • OVERVIEW • Dobros, resonators, banjos, and 7-string ‘Russian guitars’ often take ‘repeated’ open G tunings – such as ‘looping’ a G-B-D major triad sequence throughout all the strings in turn. Setting up this way narrows the open-string range to 19 semitones (like Standard minus a string) – but the cycling regularity simplifies the fretboard’s […]
 


• Open A (‘Spanish’) tuning •
E-A-E-A-C#-E • OVERVIEW • Matches the structure of a Standard-tuned Amaj shape (‘0-0-2-2-2-0’). Open A is like Open G’s ‘electric counterpart’ – it has the same interval sequence, but everything is raised up a whole tone (electric strings are thinner, so can go higher). Also popular amongst acoustic bluesmen of the pre-amplified era, who often […]
 


• Open Em (‘Cross-note’) tuning •
E-B-E-G-B-E • OVERVIEW • Takes the same interval pattern as Open Dm, raised two semitones higher: thus mirroring the exact note sequence of our familiar ‘0-2-2-0-0-0’ Emin chord from Standard (…as if you’d tuned to its notes rather than fretting them). Best suited to the lighter strings of electric guitars, due to the high wind […]
 


• Open E (‘Vestapol’) tuning •
E-B-E-G#-B-E • OVERVIEW • Open E follows the interval structure of a Standard-tuned Emaj chord (‘0-2-2-1-0-0’), thus making it a whole-tone-higher transposition of Open D – a general pattern sometimes known as ‘Vestapol‘ (after its use for an earnest 1854 folk song about the Crimean War, popular in ‘learn guitar’ manuals of late-19th-century North America: […]
 


• Open Gsus (‘Sawmill’) tuning •
D-G-D-G-C-D • OVERVIEW • Resembles a Standard-tuned ‘0-0-2-2-3-0’ Asus4 chord shape in terms of interval structure, giving an open, balanced sound (a sus4 is essentially ‘a root + the perfect 5ths above & below it’). Note the narrow maj 2nd interval at the top (2>1str) – useful for dropping open-string ‘cluster tones’ into your melodising. […]
 


• Open Gm (‘Banjo Minor’) tuning •
D-G-D-G-Bb-D • OVERVIEW • Resembles a Standard-tuned Amin shape (‘0-0-2-2-1-0’) in terms of interval structure. Thus qualifies as a ‘cross-note’ layout: as you can easily ‘cross over’ to a Gmaj voicing with just one finger, as ‘0-0-0-0-1-0’ (something much less straightforward in the other direction, i.e. making Gmin voicings in Open Gmaj). Note the 5th in […]
