you experts out there, a little help please? i want to put the following on to our web site which is designed for jazz amateurs and workshop players. i keep getting asked (quietly, usually) "which scale does this play in, john?"
can you tell me of any errors i've made? i might not have got all the us chord symbols for example.
the site is www.jazzsmugglers.com if anyone out there wants to link their site with ours could you tell me and i'll put their site on ours, so long as it is on topic as they say.
also if anyone wants to copy this material for their own pupils then please do so. you don't need permission from me. (it would be nice if you gave our site a mention, but you don't have to. anyway, if you do, then thanks.)
i'd be grateful for corrections - please use tlc. i'm just an amateur trying hard.
which major scale are we in?
introduction
i thought this was going to be easy. i was wrong.
one of the problems for newcomers to jazz is to determine where their solos should be positioned. keys change throughout a song. scales are often ambiguous, two or three different scales can be used over different sequences of chords. notes used outside the scale are very common indeed. but you’ve got to start somewhere, and the major scale is the most common place. not the only place – you may have minor scale sequences too, but let’s keep that for another time.
one tip. the key signature at the start of a song may not be a reliable guide for the overall feel of the piece. have a look at the last chord of the song. that’s the basic key in which it has been set. it will nearly always resolve there.
in this, we’ve put in the scale notes, the chord symbols, and the modes and their names. knowing modes and names is useful but not essential. knowing scales and common chord symbols is essential.
sometimes a song can be played using all one scale – autumn leaves. sometimes a song just uses a different scale in part of the bridge – blue moon. sometimes a song uses many changes – all the things you are, to those in the know, “all the chords you’ve got.” sometimes the changes just move together easily and there is only one note different between one scale and the next. blues sequences are like this, and this is one reason why the blues is so popular for musicians of any standard.
you can have too much theory, and it can stop you playing. jazz theory is often invented after you have played it. “you played a tritone fifth substitute there” “oh, did i really, i just thought it sounded nice” chet baker once sat in with my pal terry seabrook in a gig in the south of france. played brilliantly. afterwards he said, “what key were we in then?”
do you have to read music to play jazz? it depends. if you play in a rhythm section, guitar, piano, bass then you’ll have to read chord symbols. if you play any melody you’ve never heard before, then you’ll have to read notes
here we go. the 7 modes of the c major scale
please carry out the action then read about it. one action at a time.
1. the i mode. please play c d e f g a b c
as you know, you’ve played the cmaj scale.
1st problem. this scale is written either as cmaj or as c or as cwith a little triangle. it depends upon who has written the music in which country. usa chords are written slightly differently from british chords. c is the root note of the chord, also the tonic of the scale, and the chord is called the ionian. who cares.
it gets worse.
2.the ii mode of cmaj. please play d e f g a b c d
you’ve now played the dorian minor scale. this is written almost exclusively as dm
same scale as cmaj but starting on the 2nd note.
it gets a lot worse.
3. the iii mode of cmaj. please play e f g a b c d e
same scale of cmaj this time starting on e. this is written as an em chord. the 3rd mode. called the phrygian, but few people use the term. not quite so common in jazz, this scale.
problem. chord symbols are ambiguous. the same chord symbol can occur in different scales. to know which scale you are in you have to see the relationship of several chords together. such as a ii v i sequence. the most common in jazz.
your head will begin to hurt now. this em chord could be in the cmaj scale, but if you think about it you could also be in the dmaj scale, where the em chord would be the dorian, ii mode. don’t say i didn’t warn you.
4. the iv mode of cmaj. please play f g a b c d e f
cmaj scale, 4th mode. this is called the lydian major, and is not uncommon. it is sometimes used to play a variation on a major scale.
the chord symbol is either f+4 or f+11 or it can be fmaj+4 or fmaj+11. sometimes a melody requires a +4 chord to be played because this is the note used in the song.
the +11 is the same note as the +4. so if you see the chord symbol f+4 or +11 you are still in the cmaj scale.
so just remember when you see fmaj +11 you are not in the fmajor scale. you are playing the iv mode of cmajor
the chord voicing f a c e is the arpeggio of the f+4 scale and the fmaj scale, the 1/ 111/ v/ and v11 notes. if you want to play a solo, the most melodious phrases can be found from using notes from the arpeggio of the chord, the 1st 3rd 5th 7th (plus the 2nd note is sweet. the occasional use of the blues bv note is nice, too. or the pentatonic.
(i warned you.)
sometimes you see these mode numbers written down in small capital letters not large. there is a reason for it, but it is obscure and does not matter unless you take exams in jazz theory.
5. the v mode of cmaj. please play g a b c d e f g
this is the g7 scale. it is sometimes written with a g13 chord symbol. there is a pattern developing here. you’ll notice that it is very easy to carry out the action, total simplicity actually, but the explanation of what you’ve just done is complicated. that’s jazz, and is the reason why most people play by ear rather a lot of the time, and do not worry about the theory.
the problem is that it is helpful to know which scale you are in and which one runs over several chords. you must pick up the time when the scale changes otherwise you’ll sound awful. you get the clue from the chord symbols and the pattern they establish.
this mode, the v, is great, a lifesaver. this is the only unambiguous chord symbol. it is the only one which tells you for an absolute certainty which scale you are in. it is the dominant chord, in what is known as the mixolydian mode. (meaning? don’t ask).
have a rest.
let the next couple of paragraphs drift over you a bit. don’t try to work it out. i’m showing what the cathedral will look like after you’ve put enough bricks one on top of the other.
you’ve covered the most common chord changes used in jazz. these are the 11 (dorian) and the v (mixolydian) and the 1 (major).
they can get mixed up in different ways. play a bar each in c major 11/ v/ 11/ v, then change the key to f major, then play 11/ v/ 11/ v again in the new key. you’ve played the first four bars of loverman, without resolving to a major chord at all. you’ve also used two different major scales, c and f. there is only one note different between them. b and bb. so it is not quite so hard as you thought it was. playing it is easy. thinking about it is hard.
play f7, for two bars, then change the scale (very slightly, only one note different) to bb7 for a bar then back to f7 for a bar. you now played the first four bars of the most common chord changes in blues. blues scale changes follow a distinct format, basic blues are very simple in their chords which is why amateur rock players can follow them without knowing many chords.
f7 is the v mode of the bb major scale, but people playing blues just think of mixolydian modes all the time. they never resolve to a major chord, that’s what give blues its distinct sound.
back to the modes.
you’ve got two more modes of the cmajor scale to do. neither of them are very common but they are used sometimes.
6. the v1 mode. play a b c d e f g a
you’ve now played the aolian minor scale. this is written as am. same scale as cmaj but starting on the 6th note.
it is a real nuisance i know, but you can see how, when you look at any m chord symbol, then you cannot be sure what scale you are in. in the cmajor scale you’ve got dm, em, and am the 11 the 111 and the v1
look at it another way. when you see the am symbol, you could be in c major (the v1 mode) or the g major (the 11 mode) or the f major (the 111 mode). same with the other m chords.
however the other chords around it will tell you which major scale you are in, particularly the v7 chord. even a major chord symbol may be ambiguous. i saw a bb major symbol in an fmaj piece the other day, and it would play better in f.
it is not too late to switch to brain surgery as a hobby.
7. the v11 mode. last but not least play b c d e f g a b
you’ve now played the locrian minor scale. this is written as bm7b5. same scale as cmaj but starting on the 7th note.
when you see this symbol you know that the major scale starts a semi-tone above the root note of the chord. one problem here is that this chord is commonly the start of a minor scale 11 v 1 series and that involves different chords and scales. however for working purposes when you see this symbol just use the major scale a semi-tone above it. that will work whether you are in a minor sequence or still in a major.
now forget it and play
why might this have been useful? when you come to a new piece you can work out what to do with it before you start. that why.
that’s it. have fun. make music. just remember that no one listening to you will ever say, “that person plays nice theory.” they’ll say, “that person plays nice music.”
