The mandolin has resurfaced in popularity on the wave of new-found interest in bluegrass- style music.
Ironically, there already was a fair amount of classical music material written for the instrument in past centuries. But the tremendous power and skill demonstrated by Bill Monroe in the early 20th century propelled the instrument into the foreground of the popular mind.
We are lucky to have an abundance of skilled mandolin players around today.
Many have written instruction manuals and song transcriptions to provide a path for newcomers to the instrument.
There are additionally a number of excellent introductory write-ups that I have written to build up your skills on the instrument.
