The Butterfly – E aeolian

Basic chords

This tune is in the key of E aeolian. This means that the chords available are E minor, F# diminished, G major, A minor, B minor, C major and D major. Because aeolian is the sixth mode, these are the same chords which would be available in G ionian (major). The main chords will be I, IV and V relative to E minor, aka E minor, A minor and B minor.

As the tune is in 9/8, each bear contains three blocks of three notes. You can pick one chord for each of the three blocks if you wish. When finding the chord I, chord IV and chord IV sections, bear in mind that a section may only last a third of a bar. The tune also has three parts rather than the more usual two. Some people would call this a “48 bar slip jig” (16 in the A part, 16 in the B part and 16 in the C part).

In the A part of the tune, the last block of three quavers in bar one contains one long F# note. For that reason this section could be seen as a chord V section, because of chord I, IV and V, only chord V contains an F#. For ease of playability I have used chord V’s related major. Every minor chord has a related major chord, which is two above it in the key scale, and these two can always be used interchangeably.In this case B is the fifth note in the scale of E aeolian, and two notes above it is D, so D major can always replace B minor.

The last three quaver block of bar two contains the notes “F# E D”. The notes of a D major chord are D, F# and A so this section is firmly a chord VII/ chord V (recall that these two are interchangeable) section.

In bar 4 I could have continued to play E minor, but I have replaced chord I with chord IV, A minor. This works because you can play chord IV in place of any chord I section.

In the B part there are no sections which sound particularly like they need a chord IV or V. In slip jigs, because each bar contains three block of three quavers, and hence three foot taps, the usual rule about playing chord V on every seventh foot tap (whch applies in all other time signatures) becomes “Play chord V at least on every sixth foot tap, potentially for the whole fourth bar”. It’s not as snappy a rule, but it does the job! In this case, bar two contains the notes “A B B B A B D B A”. Only the third of these three blocks sounds like a chord V section to me, so I have played chord VII, chord V’d related major (Bm, chord V, would also have been fine, but it’s harder to play at speed).

In bar four however we find the notes “B – D G – E D B A”. This is much more clearly a chord V section as chord V, Bm, contains the notes B, D and F# and most of the notes in this section are either B or D.

In the C part we find a different melody but with a similar harmonic structure to part A.

Basic substitutions

In this version’s A part I have used D and Bm interchangeably. You can always swap chord V to its related major in any mode other than ionian.

In bar four I have replaced an E minor (chord I) with C (chord VI). This works because as well as its related major, whose root is two above its own in the root scale, a minor chord can also be replaced with the major chord whose root is two BELOW it in the root scale. This works because a C chord contains C, E and G and an E minor chord contains E, G and B- the two common notes make these two chords a valid substitution pair.

In a slightly more unconventional move I have begun the B part on C instead of E minor. I usually say you should start sections on their key chord (unless the melody clearly dictates otherwise) so that the listener has a firm idea of what key they are in. However, when playing in minor keys it is often nice to build tension by beginning a part on the chord whose root note is two below chord I’s in the key scale. In this case I deliberately avoid playing chord I anywhere in the section, always substituting it to C. This creates tension which then adds energy when chord I kicks back in in part C.

In the C part I have again replaced Em with G. I have also ended the section on chord IV. This can be a nice way to end an Irish tune- finish on chord IV instead of chord I! If you are in any mode other than ionian this will add a kind of lift to the end (try it in dorian and mixolydian too). If you are in ionian on the other hand it will leave the listener with a kind of wistful “grass might be greener on the other side” flavour.

Jazzy substitutions

In this version I have replaced each of the available chords in the key with the “right kind of tetrad”. In the simpler versions I used the more common three note chords called triads. These contain just a root, 3rd and 5th. A tetrad is a four note “jazz” chord which contains a 7th as well.

E aeolian is related to G ionian. Therefore the tetrads available are the same in both modes, aka:

G major 7

A minor 7

B minor 7

C major 7

D7

E minor 7

F# ½ diminished (rarely used in folk music- we’ll replace it with chord V in the first inversion, aka D/F#)

So for our tune in E aeolian, the options are E minor 7, D/F#, G major 7, A minor 7, B minor 7, C major 7 and D (dominant) 7. These simply replace the equivalent triad from the old progression, so D becomes D7, G becomes G major 7 and so on. Bm11 is a B minor 7 chord with the 11th (4th) note from a B natural minor (aeolian) scale added to it. This works fine in the key of A aeolian because Bm’s 11th is E, which of course is a note from the E aeolian scale. Adding any note from the key scale to a chord will just give you a jazzier sounding version of the same chord, and Bm11 is much easier to play than Bm7! The same goes for C major 13.

In bar four of the B part I have used a chromatic link from C maj 13 up to D7. Any time you have two chords in a progression whose roots are separated by a tone, you can create an ascending chromatic link between them by using a diminished or ½ diminished chord whose root note is on the semitone between the two original chords. In this case my progression goes Cmaj13 – C#1/2dim. – D7.

In the C part I have used a slightly unusual technique to create a “shimmery” sounding version on the part’s repeat. I replace chord I (Em7 in tetrad land) with chord IV from E dorian instead of E aeolian, aka A7. In this case I have left the top two open strings in the chord, to give me A9. This works well because the top two strings are B and E, the 5th and root of my key scale and adding any notes from the key scale to a jazzy chord will just give you an even jazzier version of the same chord. If you are playing a tune in the aeolian mode, you can often borrow chords from the dorian mode in order to give a moment of optimism to the tune. This works because Irish tunes in minor keys very rarely contain the sixth note of the scale, and it is this note which differentiates the dorian mode from the aeolian. In this case E aeolian should contain A minor 7 as its fourth chord, but I have used chord IV from E dorian, A7, instead! In dorian or aeolian you can always experiment with replacing chord I with chord IV from the other minor mode in order to create tension. If you are in the aeolian mode then dorian’s chord IV will sound bright and shimmery. If you are in the dorian mode then the aeolian chord IV will sound dark and regretful.

Reaping The Rye – E aeolian

 

Basic chords

This is a very dark sounding slip jig in E aeolian. That means the chords available are E minor, F# diminished, G major, A minor, B minor, C major and D. This is because aeolian is the sixth mode, and therefore E aeolian contains the same chord options as G ionian (major) would. You can find out more about this in my first book, Backing Guitar Techniques for Traditional Celtic Music.

In the A part I have used only chords I (Em) and V (Bm). In a slip jig you can have up to three chords per bar, one chord for each block of three quavers (“8th beats” for Americans). You usually end the second bar with chord V and always end the fourth bar and multiples thereof with chord V going back to chord I. This is exactly what I have done here.

In the B part, I have replaced the B minor with its related major. This is a little easier to play and in my opinion sounds nicer in context. You can always replace a minor chord with its related major, the chord whose root is two notes above its own in the key scale. In this case we are starting from B, and two notes up the key scale of E aeolian we find D. Therefore we can replace B minor with D major.

Simple substitutions

In this version I have replaced the B minor at the end of the second bar with a D major. This works because D is B minor’s related major chord. I have played the D in the first inversion, with the F# note (the chord’s major 3rd) at the bottom. This sounds nicer than a normal D chord, because it is getting rid of the big jump in the bass notes. In order to understand this, think about an E minor and a D chord as two separate piles of notes, which create little melodies between themselves. Going from an E minor chord, which contains a low E note on the bottom string of the guitar, all the way up to the D string which is the lowest note in a standard D chord, is a huge leap for the ear. If you invert the D chord so that its lowest note is the F# on the bottom string’s second fret then you have made the jump a lot smaller. This will “glue” your chord progression together nicely. You can play D/F# with a standard D major shape- just loop your thumb round the back to that it depresses the second fret on the bottom string as shown below.

In bar four of the A part I have replaced an E minor with a G. G is Em’s related major (E – F# – G) so this is a valid substitution. It also follows the melody, which contains the notes “G – A B E D E – -”.

In the B part I have used D’s first inversion again in bar two. In the third bar, I have substituted C for E minor. This works because any chord can be substituted either for the chord whose root note is two above it OR two below it within the key scale. In this case our key scale, E aeolian, can make the chords E minor, F# diminished, G major, A minor, B minor, C major and D major. This means our E minor can be substituted to either G major or C major.

In the fourth bar of the B part I have flagrantly disregarded my own rule about chord V! Ending a section on chord IV gives it a deliberately unfinished feel, as if it’s day-dreaming about something that might happen down the line somewhere. In this context I thought it sounded rather nice- you can experiment with this in any tune in any mode. The second time through the A part however I do not end on chord IV as the tune would sound unfinished if I did so. Instead I go from chord V (Bm) back to chord I as usual.

Jazzy Substitutions

In this version I have more or less just converted each chord from the previous version into the relevant kind of tetrad. E aeolian contains the same notes as G ionian would. The list of tetrads available in G ionian would be:

G major 7

A minor 7

B minor 7

C major 7

D7

E minor 7

F# ½ diminished (rarely used in folk music- we’ll replace it with chord V in the first inversion, aka D/F#)

The same list applies to E aeolian.

In the B part I have used a C major 9 chord. So long as you have started out with the right kind of tetrad, adding further notes from the key scale to any given chord will just make it sound jazzier. In this case I have taken a C major 7 chord (containing the notes C, E, G and B, the 1st, 3rd, 5th and 7th notes of a C major scale) and added the 9th note as well, aka D. This works fine because a D note appears in the E aeolian scale so will not clash with the tune.

The Choice Wife – D mixolydian

Basic chords

This slip jig is a five part-er in the key of D mixolydian. That means the complete list of chord options will be D major, E minor, F# diminished, G major, A minor, B minor and C major. As slip jigs contain bars of nine quavers (8th beats for American viewers) and those are subdivided into groups of three, this means that there are three potential chord slots per bar.

Compared to the other three “celtic” modes, the mixolydian is a bit less definite about HAVING to go from chord V to chord I to finish sections, and this tune is really rather vague in terms of which chords are outlined in the melody of which bars. For this reason my basic chord choices for this one might seem a bit unorthodox.

In the A part I have switched to a C chord for the last three quavers of the first bar. This is because the melody plays a long C note for the whole of this section. I have stuck with the C until resolving to D at the end of the second bar.

The B part actually ignores the first rule and follows the dominant G in the melody at the end of the second bar. It is common in mixolydian to end a section on chord IV- you can experiment with this with other mixolydian tunes.

The C, D and E parts exhibit a similar disregard for the first rule of folk tunes (chord V goes on every sixth foot tap) and so I have more or less followed the main dominant note in each three quaver section (aka three potential chords per bar), trying to keep the rate of harmonic change fairly slow to make life easy.

Basic substitutions

In this version I have broken up long sections of chords using substitutions. In many cases I have substituted major chords for their related minors (the chords whose roots are two below their own in the key scale, eg Am replaces C, Bm replaces D, Em replaces G etc), or minor chords for their related majors (the same but in reverse- C replaces Bm, D replaces Bm, G replaces Em etc).

I also use the first inversion of chord I to link to chord IV. In the B part for example I play D – D/F# – G. D/F# is a D major chord, inverted so that the lowest pitched note in the chord is its major 3rd, F#. This sets up a nice walking bassline, D – F# – G and links the D up to the G for a more fluid sounding chord progression.

Jazzy Substitutions

In this version I have taken an approach I like to play with in order to discover new chords. I have picked a note from the key scale, in this case E, the second note in the scale of D mixolydian, and left it ringing in pretty much every single chord in the tune. In this instance its easy to do by leaving the top E string unfretted. I have also kept my third (ring) finger on the D on the third fret of the B string as much as possible, as a handy pivot about which to change at speed. Again this gives some interesting and unusual jazzy chords, shown below.

In the third bar of the B part I link C major down to its related minor A minor by using the chord below the target minor chord in its first inversion. This is a very common trick to link a major chord to its related minor. In this instance I play a C (with extra notes) followed by G in the first inversion (aka G/B) and finally A minor.

At the end of the B part I have used a very cheeky F major 7 chord. This is borrowed from the dorian or aeolian modes and really shouldn’t be in a mixolydian tune at all… However as there is no F# note in this bar, the minor third note relative to the key centre D (F) doesn’t clash with anything and putting this chord at the end of the tune gives the progression a kind of blues-y throwaway feel which I really love in mixolydian tunes. You can experiment with this in other mixolydian tunes, but use it sparingly! If your ears tell you it doesn’t sound right then try it somewhere else.

The other substitutions in this version are standard tetrad additions- D mixolydian contains the same notes, and therefore the same potential tetrads as G major:

G major 7

A minor 7

B minor 7

C major 7

D7

E minor 7

F# ½ diminished (rarely used in folk music- we’ll replace it with chord V in the first inversion, aka D/F#)

As we are in D mixolydian, the correct order would be:

D7

E minor 7

F# ½ diminished or D/F#

G major 7

A minor 7

B minor 7

C (dominant) 7

Notice that in any mode other than ionian the VII chord ALWAYS becomes a dominant- in this instance our C major 7 from the key of G major has become a C7 in D mixolydian.

Please note that the “D/F#” shown below has the E string left in for continuity, so strictly speaking it should be called “D add 9/F#”. If you leave the E string in the B minor as shown below then it’s really a Bm11. Either that or a Bm7 would be fine, as adding extra notes from the key scale to a chord just gives you a jazzier sounding version of the same chord.
