First question: Which scales (if any) do you already know? And when you say "know a scale" what does that mean to you? Can you play that scale? Sing that scale? Read that scale? Write that scale? Know that scale is being used when you hear it in a song on the radio?
I recommend every student should learn 15 major scales and 15 minor scales, for a total of 30. If you learn 1 scale a day (just 7 notes), you can learn them all in a month.
For your cognitive style, how do you learn best? Is it easiest for your brain to remember shapes, numbers, letters, sounds, images, patterns, etc.?
I have a pretty good amount of experience teaching the scales using different methods. Let's find a learning method that fits your skill set.
For example if you are a "numerical" thinker then I would start off by explaining that every major scale follows the same numerical pattern 1-2-3-4-5-6-7-8. If you are playing C Major scale then the note C gets the number 1. Or if you are playing Eb Major scale then the note Eb gets the number 1. Does that make any sense to you, or do you personally prefer a non-numerical learning style?
Another example is the song "Do Re Mi" from the musical
The Sound of Music. This song is a great way to learn the major scale, if you are an "auditory" type of learner, who learns best through sound. Do you know this musical and have you ever sung this song, "Do Re Mi"? Or do you personally prefer a non-song-based learning style?
So you can see, there are many ways to learn the scales. Let's figure out a way that works best for you.
