How to learn all keys.
1. Major Scales in every key. If you know major scales you will know the minor. Just have to work on fingering.
3. Learn the circle of 4ths and 5ths and the relative minor chords. You need to know how the keys relate. You will understand this more and more over time.
4. Learn basic progressions: 1-4-5, 2-5-1, 3-6-2-5-1, 1-7-3-6-2-5-1-4 in that order. This is the mysteryman method.
All you need is a basic understanding of number 3 and 4 if you are a beginner. The knowledge will come over time.
Great points because I am a beginner and do not play the keyboard piano well. However, I am learning how to play by the "numbers system" because I do not know how to read sheet music. For instance, the longest progression underlined on the list works well for me. I added the numbers "1" (or my starting point) and "4" on that progresson because it leads me to the next key on the circle of forths/fifths chart. For those who do not know the circle of forths/fifths, it is like a clock. From 12 o'clock, the note/key/scale is in "C Major." The following major keys going counter-clockwise are:
C, F, Bb, Eb, Ab, Db, Gb, B, E, A, D, G, and back to C
http://www.jakehertzog.com/files/circle_of_fifths2.jpgI start in the key of "Bb Major" and work my way around the circle of forths/fifths to get back to "Bb Major." The "numbers system" works for me because it is universal meaning if I learn something in a key (C Major for example), I can plug in the notes, scales, and (three-fingered) chords (that is all I can play at this time) with numbers and play the same thing for the other keys. That would be my transposing. To me, point number "1" made by the poster I quoted is the most important thing to know when learning how to play by the "numbers system" because it can cut down someone's learning time by a lot. So far, I played in the major keys of C, Db, Eb, F, and Ab in church services and just started practicing in "G Major" yesterday because one lady has been visiting our church for
a week (and it took that long to find out what key she was singing). Any advice on quickly figuring out the key people sing in would be great. I do not know if the keyboard at my church has a tranpose button on it. If so, I would not know how to use it. That is my challenge from transposing. This year, I downloaded over 50 songs and I just wanted to say thanks to those who post them. Finally, as many folks here know, real musicians play in every key.
