I was reading through this lesson on UG about the Circle of Fifths. Now the guy said:

C major- No flats/sharps
G major- F#
D major- F# C#
A major- F# C# G#
E major- F# C# G# D#
B major- F# C# G# D# A#
F# major- F# C# G# D# A# E#
C# major- F# C# G# D# A# E# B#
*****************************
C major- No flats/sharps
F major- Bb
Bb major- Bb Eb
Eb major- Bb Eb Ab
Ab major- Bb Eb Ab Db
Db major- Bb Eb Ab Db Gb
Gb major- Bb Eb Ab Db Gb Cb
Cb major- Bb Eb Ab Db Gb Cb Fb

But how can you possibly play E# or B# on F# major and C# major? Following his logic, F# major would be F# G# A# B C# D# E# F, but that clearly doesn't make sense to me. Now I thought about Gb major, but Cb isn't possible either. It might be a stupid question but he clearly doesn't explain anything about it. Following the WWHWWWH pattern, it makes F# G# A# B C# D# F F#, but I also know that notes aren't repeated in scales, so it's loosing me.

How would that work?

You have 2 options.

1. Tits.
2. GTFO.

What's wrong with the key of F#? A key can have the notes F# G# A# B C# D# E#?

I really don't get what you're asking.

Gb major = Gb Ab Bb Cb Db Eb F
Cb major = Cb Db Eb Fb Gb Ab Bb

There's no Cb or Fb on the fretboard. How are you suppose to play those notes?

Are you sure?

If you flatten a note you just bring it down a half-step (on guitar, a fret). So play C on your guitar, go down a half step, you have Cb. You may also know that note as B but you're really playing Cb. The term for those notes is "enharmonic". There tone is the same but in the context, they are different. Same thing for Fb/E, D#/Eb, C#/Db, etc.

Okay I understand now. The guy in the lesson didn't bother explaining this part. Thanks.

No problem. If you have any more questions, feel free to ask.
