Since the introduction of the DVD there has been a massive rise in the range of titles suitable for all musicians. Teach yourself an instrument DVDs cover most instruments including guitar, piano and keyboards, drums and many more.
The advantage of the tutorial music DVD is that you can learn at your own pace and if you don't get it first time you can very quickly rerun that particular section. Seeing how it is done makes it far easier than just being told and you can fit it in at a time that suits you.
Many popular musicians have also produced their own DVDs to show you how they play and achieve their own distinctive styles.
