Power metal
Power metal takes influence from heavy metal and speed metal, and often emphasizes clean, melodic, high-pitched vocals, and fast pacing that is mostly driven by double bass drumming and melodic lead guitar. The rhythm guitar is defined by straight power chord progressions. Sometimes, harsh vocals are used, but usually only as backing vocals. Power metal lyrics usually involve fantasy themes. The songs often have a theatrical, epic, and emotionally "powerful" sound. Power metal is generally more upbeat than other metal genres, seeking to empower the listener and inspire joy and courage.
