Re: two more chord questions
Robert -
just a reminder about WHERE chords originate - that's in the SCALE.
and the most important place to start is the Major Scale, one of those
things we all learned in kindergarten, and can probably sing passably,
the good old DO-RE-MI etc.
the single most important thing about that scale is the spacing
between each note and the next - the pattern of whole and half
steps. ALL the other scales you ever deal with use a naming/
numbering system BASED on the Major Scale. and remember that each
note in the scale will have a distinct letter name. that's why a
note MIGHT be called Ab in one case, and G# in another - depends on
context.
Chords come from the notes of the scale, and have their own numbering
(SYSTEMS) - one has to do with the Root of the chord, and it's
relationship to the KEY that you're in. and the other has to do with
the exact construction of each chord.
ignoring the "why" for now, chords are constructed in what's called
"thirds", that is, a note, a skip, and then a note (which would cover
three different notes and their letter names. numerically, that
would amount to 1-3-5-7-9-11-13. notice that when you construct a
chord using 1-3-5-7, you have skipped the 2,4, and 6, which become
9-11 and 13 up an octave.
the "quality" of the thirds changes from point to point because of the
steps and sometimes HALF steps. that means that a note can be 3
letter names apart, for instance E to G, and involve a MINOR third,
unlike C to E, 3 letter names apart, and involving a MAJOR third.
what i think would help you immensely would be to start memorizing
chord spelling. for instance, the E7 being discussed would have E as
it's root, then, the third would be 3 letter names higher (G something
- in this case, G#), then 3 more letters to the fifth of the chord -
(B something - in this case, just plalin B), and then 3 letters higher
would give you (D something - in this case, just plain D).
want the 9th? 3 letters higher gives you f something, in this case
F#.
anticipating the question as to HOW YOU KNOW what the actually note is
- go back to your MAJOR SCALE, and observe the relationships between
the notes - if E is "one" (the ROOT), then the "two" has to be a WHOLE
STEP up - which makes it F#. an octave higher, it would be called
the ninth.
all of it is relatively simple - it's just that there's a LOT of it.
HOWEVER, all 12 keys work exactly the same, and most people tend to
play in about 4 or 5 keys, which reduces your task by a large
measure. and the other keys all can be figured out, if you need to
play something in G flat, or a less common key.
Chord NAMING is an exact science, but can create an animated
conversation amongst guitarists from time to time. for example, the
discussion as to whether a minor chord can have a suspended fourth,
when, generally speaking, a suspended fourth takes the place of a
3rd. you can certainly play a chord that has both a third and a
fourth, but the terminology can be the source of endless
ridiculosities.
please refer any discussion of minor 7th suspended fourth chords to
Lumpy, along with the name of the Dylan tune it appears in....
