Publisher Desc.  What young man isn't intrigued with the river and all it offers?  This American "riverboat song" is especially suited both in voicing and with text for a group of singing boys.  In this three-part setting, Parts I and II (written in the treble clef) are limited to the comfortable singing area of  A-A (around middle C) which makes it appropriate for boy trebles and/or cambiatas (boys in the first phase of change).  Part II is best suited for cambiatas.  Part III is written in the bass clef and is limited to the comfortable singing area of the adolescent baritone (the second phase of change) of D-D (above and below middle C).   When the part drops below E (below middle C), optional notes have been added for the light baritone (boys who are in the second phase of change but whose voices as of yet have not added the lower pitches).  Part III is optional, so when sung with only the two upper parts, Part I is written for boy trebles and cambiatas, and Part II for cambiatas.   The piece may be sung by mixed groups as well, voiced SAB, SCB, SA or SC.
