This post will help the older beginner - or those that struggle with music. I learned the sayings years ago. Had years of classical and play well by ear. For those that have struggled for years , like me this may help them. I have always been a a poor note reader. When you first begin little sayings will help you and I still use them, but I have moved away from them...I became a much better music reader when I forced myself to learn the notes for what they were. Patterns have helped me. Things I have noticed: middle C is shared . D directly above and below the base clef is equidistant. Two lines down below the base clef is C. Two lines above the treble clef is C also. There are a few others that may be of assistance.
Three lines or spaces make up a fifth. (I will give a lot of info here not as a way to be erudite, which I'm not, but to fully explain terms). The fifth of C is G, so a good example is middle C (which is a line) to second line G. It works consistently. Of course this works out as fourths going down. Note that this automatically takes care of the major minor intervals. Look at the lines in treble clef EGB; the B is the fifth of E. I realize this may be old hat to many, but I want to be thorough. Pick any three lines, or spaces, they will form a major triad eg. CEG, or let's try spaces ACE; this will be the A minor triad. The beautiful thing about this is that the fifth will not change.
The third will change so that will not be a consistent way to remember your notes This is useful in a myriad of ways. The bottom clef lines are GBDFA. I see a D line and I temporarily forget its name. Now remember this bottom clef. I mentally look three lines up and see A. I now know that the note in question is D. For reference the circle of fifths is BEADGCF and is basically derived by saying what's the fourth of B? Oh E. What's the fourth of E? ( I will go in depth here for clarity) remember to go up in the key of E in this case.. so E,F#,G# A, so A is the fourth of E. So let's say I'm in the bass clef. I can't remember what the space just above the bass clef is ( it is a B), so I re go down three spaces (remember this works for lines or spaces) I go down three spaces B,G,E .. now that would be one way, but the faith is much faster.
Three spaces down is E. You don't need to go down the notes that is time consuming and makes you have to do three of four things, which will hinder music reading. Just see the space above the clef and know that's B, then think that's easy, B is the fifth of E.
I am doing this on a flip phone I hope this is clear.I have gone from reading music very poorly to just poorly. I am working on the hard parts of Fur Elise, Alla Turca, Solfegietto etc., and various things I have done years ago. I think Menuette in G by Bach is an excellent piece to learn. I also have found slow play is a good way to learn and memorize pieces.
