Three Days Grace's music has been described as post-grunge, hard rock, alternative rock, alternative metal and nu metal. Their self-titled album mostly uses the sounds of alternative metal and post-grunge. However, on their second album One-X, the band had more guitar solos and a more melodic sound.
