<div class="bbWrapper">There are sooooo many difficult songs to play on guitar. I do play classical, so I would say Segovia would difficult, Bach, and Mozart is certainly tough. Torrega and Fernando Sor will make you throw the guitar down for awhile. If you want a challenge, try to play this type of guitar. You will not be dissappointed. I find that when I practice at least one hour in this style, the electric stuff comes easier for me. Sweeps and some fast runs are a definite benefit for me.<br />

As for using my Pets...Anything by Paul Gilbert is difficult. I have actually gotten a few of his tunes down, much time in practice was spent. Try Viking Kong, Superheroes, or any of his video lessons.<br />
<br />
Steve Vai is another. Getting the notes to sing like him is my challenge. <br />
<br />
Stevie Ray Vaughn....no need to explain.<br />
<br />
The hardest song though for me was Jimi Hendrix's live version of "Machine Gun". I still have trouble and rightfully so.....this was a gift from a guitar god that I have the privilege to play (not as well as him I might add <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f609.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=";)" title="Wink ;)" data-smilie="2"data-shortname=";)" /></div>
