Musical teleology

There is just no other art so strong as a piece of music that knows where it's going...   Every now and then I hear a piece that simply captures me. The piece can be a longer work, even symphonic, or a short song.  The magical part is that it's designed to travel to a specific meaning and it effectively works to arrive where it's designed to go.   It's easy to see why Sibelius' Finlandia was the first piece that strongly struck me so. Mahler's #1 was another such. More recently, such choral pieces as Marta Keen's Homeward Bound and Nick Glennie-Smith and Randall Wallace's Mansions of the Lord. In particular, I have felt a yen to listen to Mansions a lot today/tonight.    The link above leads to a portion of the performance at Ronald Reagan's funeral. Here are the lyrics.  You tell me: is it as effective a piece as it seems to me?   "The Mansions of the Lord" Music: Nick Glennie-Smith Lyrics: Randall Wallace   To fallen soldiers let us sing where no rockets fly nor bullets wing Our broken brothers let us bring to the mansions of the Lord   No more bleeding no more fight No prayers pleading through the night just divine embrace, eternal light in the mansions of the Lord   Where no mothers cry and no children weep We will stand and guard to the angels' sleep All through the ages safely keep the mansions of the Lord
