Folk String Instruments Instruction
Since there are hundreds of books and resources here to choose from, the first step in making your choice is to narrow down the options. Filter them down to just the instruments that interest you, and you'll find the number a lot more manageable! From there, you can sort however you like - one good idea would be to check out the best-selling and top-rated books, such as the ProLine Play Today! Series, offered for ukulele, mandolin and banjo.
If you're an advanced player, you'll probably be more interested in specialized instruction than beginner method books. Focused lessons can be based on a certain artist (as in the Hal Leonard Earl Scruggs and the 5-String Banjo Book and CD Package), an entire genre (as in the Hal Leonard ASAP Bluegrass Mandolin Book and 2-CD Package) or occasion (such as the Hal Leonard Christmas Carols for Mandolin Book) - to name just three examples of subject matter. Whatever interests you, be sure to take a look; you might be surprised by the variety of purpose-made instruction materials.
The most important thing to remember about any instrument is that your playing experience is a personal one. It's up to you what instrument you play, what musical style you choose and how you decide to put your own personal stamp on it. There's one thing that's not subjective, though, and it's that getting great results starts with great information - so gear up with the right folk string instruments instruction resources today, and put yourself on the path to musical greatness!
