By using See Saw Swing and training your beginner to play the first five lines, Twinkle falls into place so easily. Go to the What Is It page to look at the first five lines. Once your beginner can hold the bow, begin by teaching E and then A, so that string crossings happen at once. Have them sing the song: See Saw, See Saw, Will you be my friend, See Saw, See Saw, Yes I’ll be your friend.
The first line asks for the first finger on the E and A strings. The second line adds the third finger. The third and fourth lines add repeats of the third finger. The fifth line adds the second finger, at which point every note is in place for Twinkle.
In fact, when you look at the sample, you will notice that by changing the order of the quarter notes, the beginner can IMMEDIATELY play a variant of the first line of Twinkle.
Most importantly, because See Saw Swing exercises the third finger and string crossings from the beginning, it becomes easy for the beginner to learn the second line.
Before I used See Saw Swing, it would take at least two months to train a beginner to play Twinkle. Now, with older beginners, it takes an hour. With young ones, three weeks.
I know it sounds like magic. Maybe it is.
