The composers intentions

Being that Watts’ piece was written as a hymnal and meant more to be sung along with rather than to be danced to and enjoyed just as the music as Tchaikovsky’s the simplicities of Watts’ piece make a greater amount of sense. Thus, the presence of straight forward mostly consonant chords in Watts’ piece also makes a greater amount of sense. Watts would have written his piece with the pianist in mind knowing they would be performing the piece and would also like to sing along and make it simple for the choir or church-goers to keep up with the lyrics and style of the piece. Whereas, Tchaikovsky wrote his piece not so that an audience would enjoy the sound of the music while the dancer could dazzle them with their steps, and if either the music or the dancing was to simple the audience would grow tired of the piece quickly which is an entirely undesirable event for Tchaikovsky, the musicians and the dance company performing.
