What is the best long term approach to learning new songs?
Currently I learn one measure and then move onto the next measure until I get all the way through the song. Depending on the song it could take me days to weeks or more to even reach the last measure. Typically I find when learning a new song, at my level of playing ability, there are only a few measures that give me trouble.
I have started to wonder, is it better to build the skill of learning a song by setting a metronome at a very slow tempo and go all the way through the song to increase my ability to read new music and play at the same time. Then parts of the song that I have trouble with I can separate and practice them until I become proficient enough to incorporate them at a faster tempo.
I do like the idea of getting to the point of being able to take a new piece of sheet music and be able to play it, but I don't know if this is best practice so to say.
