hi guys i am trying to learn zakks farwell ballard and wanted to know the best way to learn this short song is it best to break the song down in to small parts and master them befor moving on or learn the song as a whole and get better from there also in the song they is a tr 15/17 can some one tell me what this is and how i play it thanks ash :D

If your talking about a trill, you wnat to hammeron the 17 and pulloff onto the 15 very quickly and several times. If your talking about a slide, play the 15m then slide to the 17 w/o picking the 17 and sounding th1 16 along the way.
