Guillaume Veau was a thirteenth-century French trouvère.^[1] Three chansons courtoises are attributed to him in the Vatican manuscript Reg.lat.1490:^[2]

• J'ai amé trestout mon vivant^[1]
• Meudre achoison n'euc onques de chanter^[1]
• S'amours loiaus m'a fait soufrir^[1]

The first two of these are unica, that is, they appear in no other source. They both end on a note other than the tonal centre of the first four phrases. The "moderately florid" melodies of all three are written in bar form.^[1]
