Guitar Scales & Modes
Version 2.1
(c) 1990, David Sampson
This program requires Microsoft Windows 3.0 to run. When the program is
started, a guitar neck is displayed. You can toggle between an expanded
view (default) or showing the entire neck at one time. You'll notice that
on a real guitar, there are f ret inlays at the 3rd, 5th, 7th, etc.,
positions. These are shown here as white filled rectangles. The 12th fret
has two stacked rectangles. Above the guitar neck, the frets corresponding
tho the inlays are labeled to give you a quick reference.
Below the guitar neck are a few comments such as the selected key
signature
and mode. I also tell you how the scale is constructed, using the notation
of:
Root = key signature note (root note)
H Step = Half Step interval (1 fret)
W Step = Whole Step interval (2 frets)
So the Ionian mode (major scale) is constructed as follows:
Root -> W Step -> W Step -> H Step -> W Step -> W Step -> W Step
->
H Step
This means start at the Root note, then add a whole step to get to the 2nd
scale degree, then another whole step to get to the 3rd scale degree, the
a half step to get to the 4th scale degree, etc. The final half step
takes you back to the root note one octive higher than the starting note.
In some of the scales, you'll see W Step + H Step. This is a minor 3rd
interval (3 frets).
Note: When you choose a scale that has a 5th and a flatted 5th, like the
Blues Scale 1 for example, you'll see the number 5 listed on adjacent
frets. The first instance is the flatted fifth, the second is the fifth.
I labeled the scale degrees as
integers not characters, so that's one of the little problems I encountered
after I designed the data structures, wrote a whole bunch of code and then
wanted to add that scale. As long as you're aware, that shouldn't be too
much of a problem. I'l l fix that in the next revision.
