Charlie Puth has released a new track titled “Hero.” If you go to YouTube and watch Charlie break down his super famous song “Attention,” he explains how he made that track. One curious detail from that interview is that Charlie explains how he was hesitant to feature acoustic guitar as a main instrument in the song, even though he recognizes it can be really useful for filling out rhythmic spaces in a song. In his latest release, “Hero,” he does feature the acoustic guitar as almost the prominent instrument. In that interview for “Attention,” Charlie said something akin to, “If you use the acoustic guitar, you instantly become THAT guy, or the song instantly becomes THAT song.” Meaning, Charlie was thinking about the fact that the persona of an “acoustic guitar guy” takes up so much space, and it seems, in his opinion, that persona overshadows some part of the song itself.
