I found your Major Scale Chart a couple days ago, which I love, it answered a lot of questions for me.
I printed it out so I could have it hady at all times, I noticed at that time that in the key of F you use Bb instead of A#, I was curious why but didn't know how to find out, today I was reading The Major Scale Chart: Part 2 and saw that you posed the question: "In the key of F, why is the 4th note of the scale called Bb?" but you didn't answer the question so this has been prying on my mind and I would like get the reason cleared up in my mind, it won't let go of me.
Thank You, wcostley
I'm really glad this is helping out.
The place to post questions about the lessons is in the Member's Guitar Lessons and Articles forum. Once there, you'll see a link for Discussion on Member's Lessons. If you don't mind, I'm going to copy this post into that forum for everyone's benefit.
The reason I asked the question, "In the key of F, why is the 4th note of the scale called Bb?" and didn't answer it was because I needed for you to answer it so you get an understanding of what's going on!
The answer is because it's following the Alphabetical Rule, which states that the next note name of the scale will be the next letter in the alphabet (from A through G). So then my next question is why is the note name a Bb and not a B? Please give a try at the answer and if you don't get it, we'll keep talking.
Thanks for contacting me.
