Amazing Grace is truly a timeless classic! Arrangement by Animenz is of course awesome. First, it’s FREE; then we have the 3 verses with increasing complexity and beauty!
The first verse sets the theme like an anthem with simplicity. Then the deep bass develops giving you a foretaste of some beautiful chords. Then on the final verse the power is released. I can’t stress enough it’s so refreshing to have a piano arrangement of this that doesn’t play like a simple pop song with basic broken chords / arpeggios. In this particular case, the music was arranged to have great musical complexity without much of the technical difficulty.
