Although his early tutors were among the first to use the thumbpick in guitar playing, freeing the fingers to pick melody, Travis' style, according to Chet Atkins, went on in musical directions "never dreamt about" by his predecessors. His trademark mature style incorporated elements from ragtime, blues, boogie, jazz and Western swing, and was marked by rich chord progressions, harmonics, slides and bends, and rapid changes of key. He could shift quickly from finger-picking to flatpicking in the midst of a number by gripping his thumbpick like a flat pick. In his hands, the guitar resembled a full band. As his son Thom Bresh puts it, on first hearing his father as a child "I thought it was just the coolest sound, because it sounded like a whole bunch of instruments coming from one guitar. In it, I heard rhythm parts, I heard melodies, I heard chords and all this wrapped up in one." Equally at home on acoustic and electric guitar, Travis was one of the first to exploit the full range of techniques and sonorities available on the electric guitar.
