In the early 19th century, the terz guitar was so popular that the majority of duets published called for it to be the primary voice, as a guitar in E did the second voice. This is usually indicated by the notation "tierce". In Vienna, the terz guitar was especially popular. Many original editions of duets from Vienna in this time period do not specify "terz", but the guitar parts are often in different keys off by a third, which is an indication of terz guitar being required. So common was the terz guitar for ensembles, that it was assumed.
The terz guitar was used for ensemble compositions, where its treble range and brightness resulted in better projection than the guitar in E. It is often found in guitar duos, piano with guitar duos, and other combinations, including terz guitar with full orchestra, as in the case of Giuliani's 3rd concerto. The amount of music written for terz guitar in ensemble situations was vast and include compositions by Johann Kaspar Mertz and Zanni De Ferranti.
