Church Sonatas

Seventeen single-movement instrumental works by Wolfgang Amadeus Mozart are referred to as "church sonatas" or "epistle sonatas". Some are simple trios for two violins and bass, others more lavish concertante pieces with obbligato organ.

Only Leopold Mozart took up the epistle sonata in isolated pieces that have survived in fragmentary form. Mozart's sonatas thus form a musically significant repertoire without parallels elsewhere.
