What Are Intervallic Functions? (iOS 2.0)

so let's take a major scale we're going to use C for our example here a number of the notes generically one through to seven so we'd have one two three four

five six seven and back to one again up the octave if I play the notes C to G

that's going from the one up to the five one two three four five first to play C

to B that would be one going up to seven one two three four five six seven one to

seven see to D would be one to two see to e would be one to three and so on and so on now we can refer to these numbers as intervalic functions so this is the C

intervalic function of one going up to the G into valid function of five [Music] now the reason this is generic is because we can apply these numbers to any of the major scales from any other

root note so if I did a G Major scale it would also be one two three four five six seven and one again if I did an a

major scale and have one two three four five six seven one again and so on but going back to C major let's say we go

from the one up to the seven b well there is another B immediately behind this C here I could go back from C back of fret to B and this is still seven

still the intervalid function of seven and in fact anywhere on the fretboard I was to play a B while I'm thinking or visualizing of a c root note that would be Remain the intervalid function of a

seven so it doesn't matter if I go up to the b or down to the B it's still the intervalic function of a seven in the first case I'm ascending to

the seven one on up to seven in the second case I'm descending to the seven one descending to the seven and it'll be the same for all of the other intervalic

functions two all over the neck so if I was to play a d anywhere on the fretboard that would remain the intervalid function of a two so it's one

to two one to two one to two so from our original C starting point I could continue coming back down the scale so

that would be c one down to the 7B and then I could keep going down down to the 6A down to the G5 and so on and so on so

once again this would be one C going up ascending to this value function of the 5G or I could go from the 1C

descending to the intervalid function of the five which is a g the next thing we need to know is that by lowering so flattening or raising using sharpening

those numbers one to seven from the major scale we can find all of the other intervallic functions that are contained within any other chord or scale as part of the workouts solo will present you

with a note a chord or a scale and ask you to find intervalic functions based on that root note or the root note of the displayed chord or scale for example solo might present you with an a root

note and ask you to find the antibiotic functions of one and three so with the a major scale as your mental blueprint find the one and the three

alternatively in the changes trainer solo might ask you to find the one the flat three the five and the flat seven over a C minor seven chord so this time with the c major scale as our blueprint

and C as our root note reference point identify the 1 3 5 and 7 from the c major scale one three five seven and

simply flatten the three to the flat three and the Seven to the flat seven so we'd have one flat three five and

flat seven or you might be working on the E flat lydian scale and solo asks you to find the one two three sharp four five six and seven so this time with E flat major

is our blueprint and E flat is our root note reference point we simply play through the intervalic functions of one to seven but raise and sharpen that

fourth note so one two three sharp four five six seven and one now for Theory reasons that aren't

important to go into right now solo May occasionally ask you to find the intervallic function of a nine or an 11 or a 13. now all you need to know is that nine has the same intervalid

function as 2 11 has the same function as a four and a 13 has the same function as the six for example if you're asked to find the intervalid functions of a one a flat nine three and a five that

would be equivalent to finding a one a flat two a three and a five over time this process will become second nature and you won't have to use the major scale as this constant blueprint and

you'll also find that intervalid functions are an incredibly powerful way to talk about chords and scales without reference to specific note names
