'''Symphony No. 27''' in G major (Hoboken I/27) was probably written before 1760. Its chronological position was assigned by Eusebius Mandyczewski in 1907.Published in ''Joseph Haydns Werke: erste kritische durchgesehene Gesamtausgabe'' Although later adopted by Hoboken, Robbins Landon has subsequently revised the work's likely chronological position HC Robbins Landon, Haydn: Chronicle and Works, 5 vols, (Bloomington and London: Indiana University Press, 1976-) v. 1, Haydn: the Early Years, 1732-1765, 280-294. and now believes that the symphony is one of Haydn's earliest, written at roughly the same time as symphonies nos. 15-18. Haydn himself may have labeled the symphony his 16th, although this remains unclear.
