Lightbulb Theory help- Back to basics!

Ok, so in the Lydian mode thread it turns out doing some theory stuff on here will help a few people out, so I'm gonna go over some fundamentals in theory in this thread!

Before I start on other things, I'm just gonna explain a couple of things first (that might seem like I'm patronising, I'm not it's just I want this thread to help even people with no theoretical knowledge- yet):

Every possible note on most instruments are: A, A#, B, C, C#, D, D#, E, F, F#, G, G#.

Ok, now this is down to something that has a more complicated name than what it actually is, it's called an ENHARMONIC EQUIVALENT. All that means is that it's the same sounding note (or, it's at exactly the same pitch as another) but it has a different name. I'll give you a couple and then you can see whats happening.

A# = Bb
C# = Db

As there is no E# or B# in between E and F & B and C (see the notes at the top of the post). So, in fact, E# actually is the same as F!

Next, WHY DON'T THEY WRITE EVERYTHING IN SHARPS, IT'S WAY EASIER! I will write two scales below, see if this explains it:

A# Major: A#, B#, C##, D#, E#, F##, G##
Bb Major: A, Bb, C, D, Eb, F, G

See? Bb major is much neater looking, and they're both actually the same thing!

Now, you may not understand what major is or what is going on above, but don't worry, that will come with time. I have some more facts for you in the mean time:

The distance between one note and the very next one (higher or lower) is a SEMITONE, so from G to G# is a semitone, and from Bb to A is a semitone.

As you've probably guessed, a TONE is double this distance: G to A, B to C#. (It's just counting across two notes from the notes written at the top of this post!)

Ok, so there's some fundamentals, I'll leave this for a couple of days to see what people think and then I'll do another if you like !

Thumbs up Re: Theory help- Back to basics!

keep it up, john! The way you're writing, I'm sure there will be info for all, novice or advanced to learn from. Passing along knowledge is a great thing!

Personally-- can't wait 'till you get to explaining the modes and relation to chords as that's what I'm learning now!

The secret to success is success?

I wonder how long it will take for you to get into chord substitution?
