Here you will find some blues tunes that I just improvised. If you find some similarities between these riffs and others that you've already heard, that's normal, like all musicians I learnt this instrument by listening and trying to imitate others. I would be very pleased if you'd drop me a mail with the artist's name when you think you've heard this before.
There is no tablature here, except when someone asks me how I do a certain bit. In this case I include the time in seconds in the tune where the tablature starts.
By the way, the sounds are mp3 and real audio.
