How long does it take, in months, to learn to play harmonica ?

How long does it take, in months, to learn to play harmonica to the point where you could jam with some folks playing blues and not get pillows thrown at your head?

I’m not talking technical brilliance here – just good enough to be having fun on standard blues songs without hitting painful notes or chords every other bar or two..

For the sake of the argument, assume about 30 min. per day of practice, and prior familiarity with music in general.

Thanks!

How do you learn to play blues guitar?

I have a guitar and I have even taken a class. I learned to play a few songs and how to read tabs. I have used tab websites but they don’t rate the songs on how hard they are, and I have yet to find a good site.

Ideally there would be a site that starts with little 8 bar blues songs that I can pick through, minimal chords, and then the tabs will progress to harder longer blues songs with turnarounds and licks and whatnot. Any suggestions would be great.

Please don’t just post a tab site unless there is a free beginning section.

What I am not looking for is a purely tab site unless the songs are rated according to difficulty. I am not looking for chord charts, picking exercises, or scales.

If you can be of help, I would appreciate it. Thanks!
