How much time / practice do you put into a song before saying enough is enough? I've got a folder full of songs that I've invested varying levels of time and effort to learn to try to become proficient. Trouble is, I've learnt that I'm not a good learner. I invest what I think is a high level of time and effort in each song, but eventually become bored with what seems to be little advancement. Of course I am moderately better at each tune than when I first started, but each tune is still riddled with errors. I've tried playing nothing but one tune for a fortnight (morning and night practice), and I've tried practicing 2-3 different tunes to break the monotony. What tends to happen is that after a heap of practice with little advancement, I start to look for a new tune to learn. As a result I've got plenty of tunes that are half baked. So....how long should you persevere with a tune to get it right before admitting defeat and looking for something else?
