Try this melody on any and every string.
Before looking at the answer, can you figure out the Twinkle melody? The first few notes are written below. Write out the rest. All tones can be played on a single string [any string; we are using string one]. Hint → the melody only uses tones within the E Major scale [when played on string 1 or 6]. And, 2 of the lines are the same. Note: the tune doesn't matter, it's the skill we are after. It just has to be a melody that you know you can sing (hum, think...have something to compare sounded tones against).
