Symphony No.27 in G major, Hob. I:27 "Hermannstädter"

Joseph Haydn's Symphony No. 27 in G major (Hoboken I/27) was probably written before 1760. Its chronological position was assigned by Eusebius Mandyczewski in 1907. Although later adopted by Hoboken, Robbins Landon has subsequently revised the work's likely chronological position 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.
