Amazing is a huge classic power ballad from Aerosmith from their 1993 album "Gotta Love It". It's a very big and epic song with an iconic introduction that really showcases Joe Perry's signature style of playing the guitar. The riffs throughout the song are pretty sparse throughout and mostly just simple chord hits. Theres not necessarily a definitive rhythmic guitar part. Instead it makes use of arpeggios to fill out the space, giving the guitar a more ornamental role instead of a solid rhythm or lead part. In addition, it uses a lot of blues guitar shapes and a lot of chord shapes based on having the root on the fifth string to change up the voicing and sound which gives this song an interesting sound and challenge.
