Thanks! Share it with your friends!


This video details how to use the Circle of Fifths to calculate key signatures for major keys. It’s important that you know how to create the circle before watching this video – please watch my other video on “how to create the circle of fifths” before this one if you need to.

If you’d like to extend your knowledge of the circle and use to it create major scales have a look at this video:

Please note that this video is virtually identicial (bar a few small changes) to my previous video detailing how to use the circle of fifths for major keys. This video, however, is in HD and has much better sound quality.

Thank you. I would like to understand something C#M at around 6.40 on this vid, you go from C around the sharps, but why , there is not a reason other than to fit some understanding to it right? Every now and then on my journey of learning music theory something happens that is like a glitch in the matrix, with no real reason just that that's the way it is done. Or it's the easiest way to explain it, ok that's reasonable. I know I am a beginner really, but it's like we are trying our best to put words and explanations on to something not designed that way and I notice that every now and them , a big gap appears and there is no logic to it, it just … er is. Thanks I love your work it helps me so much, I think you are the best at explaining theory especially to some of us who need that extra clarity.I didn't think I would ever manage to learn any of it but it's getting easier. Thank you. I have told all my classmates.

thank you so much! I'm doing my homework and I couldn't understand ANYTHING

Brian Marais says:

Thanks for explaining it so well! But please forgive my noobish mind… but how do you work out A# Major? Would you use the Bb Enharmonic, which is 10 "notches" away on the sharp side? And what would all the sharps be, because surely there are no more notes to sharpen? Or is that just a little too advanced for me at this stage?

Thanks for explaining so simply and perfectly

Kavita Kamesh says:

Very nice explanation. I have one question though. What do you mean by E# and B#. Technically these notes do not exist right ? We go from B to C and from E to F.

OMFG I LOVE YOU!!! My tutors couldn't teach me, my teacher couldn't teach me, most of videos are SOO confusing! And you are AMAZING! Why can't people explain things like you do:))) instead of making things more complicated

Carlos Noriega says:

-Daniele - says:

I'm a visual learner, and thank you thank you thank you so so so much. I understand!!!! You explained it extremely well!

Andrew Nguyen says:

I honestly don't know whether or not this is a dumb question, but, how do you find the scale for keys that's not on the circle of fifths? like A sharp major?

Wago Howard says:

Good job buddy taking this approach to teach in future!

Tony Dinh says:
