I am trying to transcribe a little song and I am facing a problem: I am realising that there are several ways to write it, 2 ways to be more specific; Here are 2 images (I just wrote the first few measures of the song):
Which one is the right one? If I get rid of the metronome, and just listen to each sheet, they sound absolutely the same... How can I know and decide which way to go among these 2 possibilities? I have no idea what I should do, and have the same problem every time I am writing a song.
Another example, I have the same problem with "Ode to Joy": should I use the first notation, or the second one? (the last one would make the sheet music very long, so I guess it wouldn't be the right choice)
I'm very confused, if somebody could help me with this I would be very grateful.
PS: For the first song, I chose the first version (with the quarter notes), but when searching on the internet for the song, I realised that it was written the second way (with the eight notes)...
