The first instrument I learned was the piano, where having sheet music in staff notation is sufficient to know exactly what you need to play. Lately, I started to learn the guitar and the harmonica, where things are -- to me -- less obvious and where I can certainly understand the usefulness of tablatures.
I started tabbing a few songs for which I already had the sheet music, because I find it hard at my level to simultaneously worry about reading, actually playing the note(s), and keeping track of my breathing (on the harmonica) so I don't choke before I'm done playing.
However, I'm wondering whether such an approach is advised, because I'm worried that it will slow me down in learning how to sight-read on the harmonica. Should I keep going this way, or should I start early on to try and get rid of the habit of relying on tablatures?
