Q: okay I've done what you said (https://imgur.com/a/Kgoef). Question: is there a convention for how tall the beams on beamed notes should be? or can you just do whatever? thanks again- we're getting to the topics that are brand new to me and that's pretty exciting
A: your notes look about the right height. ok let's try 4 quarter notes on F (the space above the lowest line). Put a sharp sign (#) next to the first note, and then a natural sign next to the last note. the result is you have 3 F#'s and 1 F natural at the end. i hope that makes sense
