Publisher Desc.  This masterwork has been adapted for singing groups containing changing voices.  An attempt has been made to maintain the authenticity of the work with only enough changes to conform to the range and tessitura limitations of early adolescent singers.  Ave Verum is one of the best known choral works of Mozart.  Preparation for performance will allow directors to teach good breath control in singing the long lines and the importance of legato singing.  The slower tempo will help the singers to administer purity of vowels for good blend and balance.  It is best accompanied by the pipe organ but certainly may be accompanied by piano in non-liturgical and secular settings.  It is rated medium-easy for early adolescent choirs who are capable of singing four-parts.  The work may be sung easily by amateur church choirs.  This particular arrangement works beautifully for SSAB adult voices.  Mozart wrote the work for his friend Anton Stoll who was a church musician in the Baden Parish outside of Vienna. It was composed to celebrate the feast of Corpus Christi and dated June 17, 1791.  The 14th century hymn-text, Ave verum corpus, is attributed to Pope Innocent VI.
