Thanks for the nice words.
If you can remember these three lines of ascii characters, fretboard maps and scales will never be very hard for you.
C C# D Eb E F F# G Ab A Bb B C
The first line is called the "C Chromatic scale", apart from being a template for all chromatic scales, it shows the notes along your C string. So if you write:
down the page and fill in the chromatic scale after each letter, you have a fretboard map for GCEA tuning.
The second line is a template for every major scale, apart from being the C Major scale. You overlay it on the chromatic scale template to get the notes in a major scale.
C D E F G A B C Major template
C C# D Eb E F F# G Ab A Bb B C Chromatic template
A Bb B C C# D Eb E F F# G Ab A A chromatic scale gives A B C# D E F# G# A as A major scale (sorry they don't line up well on this editor, but you can get the idea)
The third line is the Natural Minor template and you use it like the major template to find the notes in natural minor scale.
So when you know the notes in the scale, worked out from the three templates and your fretboard map, you can look at making a chord. Which is as easy as D F A C. So you look at the C major scale template:
C D E F G A B C and want a chord to go with D or a D type chord, so you start at D and pick the notes D (skip E) F (skip G) A (skip B) C = DFAC, find DFAC on your fretboard and you have a chord to use with the D note in the melody. Or a D type chord to go with a C major scale. It is actually called Dm7, but you don't really ever need to know the name, when you are famous you can pay one of your people to write out the chord names, all you need to know is the names of the notes and where they are on your fretboard. Then you can arpeggiate, punctuate, shape etc chords as you feel like.
So even if you are old and easily bored, you can learn three ascii sequences and discover a lot about your fretboard and uke and music without ever opening a book or looking at the tangle, sorry circle, of fifths. Eventually, you might need a book to get to further steps, like learning the naming convention for chords so you can work out the notes without a chord chart.
