Concerto for flute in G Major No. 1

G.B. Pergolesi: Flute Concerto in G major No. 1 was written around the 1730s – 1740s. The status of the flute concertos attributed to Pergolesi is one of the most famous cases of disputed authorship in Baroque and Classical music scholarship. Most modern scholars, including those contributing to the New Grove Dictionary of Music, agree that these concertos were likely not composed by Pergolesi. Pergolesi died at the age of 26 in 1736. Following his death, his fame (particularly due to his Stabat Mater) skyrocketed across Europe. Publishers, seeking to capitalize on his "brand," frequently attached his name to works by lesser-known or anonymous composers.
Research suggests the Concerto in G Major may actually be the work of Giuseppe Tartini. This stems from evidence found in 18th-century manuscript collections, found in the library of the Royal Swedish Academy of Music in Stockholm, and stylistic analysis that aligns more closely with the Venetian school than the Neapolitan style of Pergolesi.
Pergolesi was primarily a composer of vocal and sacred music. Instrumental concertos are extremely rare and "doubtful" in his authentic output. Conversely, Tartini was a prolific instrumentalist who composed over 100 violin concertos and several flute concertos.
Additionally, the G Major Concerto reflects the Galante style, which bridges the late Baroque and early Classical periods. This style was more characteristic of the northern Italian (Venetian and Paduan) tradition led by Tartini during the mid-18th century, well after Pergolesi’s death in 1736.
