In this video Jason Vieaux identifies some common trouble spots when learning how to play the famous Spanish guitar song "Leyenda". Many people often get confused by the distinction between classical guitar and Spanish guitar.  Since Jason is an expert, we had him explain the difference: 

I find that my travels now are great opportunities to tell people I meet in airports, planes and hotels about my online classical guitar lessons at ArtistWorks. Whenever I'm asked, "do you play in a band?" whilst on the road, I often respond that I play "Spanish Guitar", only because it's an easy answer in a busy world.  Even though "Classical Guitarist" is a better umbrella description of what I do, "Spanish Guitar" puts the image into most people's minds of a guy or gal sitting, unamplified playing Spanish guitar songs or Latin American music - alone.  And yes, I do that… kinda. 

What I really do is play music by "Classical" composers from Spain and Latin America, with the requisite classical technique and musical study that is required to play it.  I also play Bach, modern, pop and jazz arrangements, 19th century, lots of concertos with orchestra and chamber music, but that's not the point.
