Can I just clarify please. Using the only using each letter name once in a scale, so if you did use the an A sharp it would read something similar to .......E, F, G, A, A sharp, C, D etc, whereas using the B flat it would be.....E, F, G, A, B flat, C, D etc
Is that correct, or am I completely misunderstanding it?
I'm not sure whether you have understood this, as you have started your F major scale with an E which is completely illogical (either that or you have intentially written the Locrian mode on E, but I doubt that).
To form a (any) major scale you must adhere to two rules:
1) You must follow a set pattern of tones (T) and semitones (S), thus: T T S T T T S;
2) You must only use each letter once, sequentially (obviously), until you reach the next octave at which point you start the sequence again.
NB, tones and semitones are intervals (distances between notes), so the first "tone" in F major is between
the F and the G, not the F itself, so: F (T) G (T) A (S) Bb (T) C (T) D (T) E (S) F
*These rules are not instrument-specific.*
Another useful rule is this:
Every major and harmonic minor scale begins with a tone and ends with a semitone. No exceptions.
I hope that all makes sense.
