"clarino" (plural: "clarini"), and its variants, came to be specifically understood as the practice of playing the natural trumpet in its high register. Range of notesSee: Natural trumpet for history of expanded tonal range.Natural trumpets were originally war trumpets used to signal with a short repeating pattern. They were largely the same among European countries, consisting of two tones, a fifth apart. Calls were started with the lowest. Before the modern naming systems were invented that allow us to describe a note with a letter, trumpeters assigned names to notes that their trumpets played. The names described a note's relationship to the other notes.Similar names were used in different countries, though the changed based on language. The first named were the lowest, made by a long horn that could only play one note. When a second note was added, it was named in relationship to the original note, as the note that follows. Although military in use initially, trumpets were put into trumpet ensembles, with places in the ensemble based on the notes they played. The basic series by the 1600s was: 1 basso (also gross or grob). This was the oldest note, sometimes called boss or master. An early trumpet could play only one note well, possibly two. That good note was a low note, and formed the bottom of a series of notes. 2 Folgant, (also: vulgano or vorgano), the "note that follows", "follower", "attendant". A single note higher than the basso. 3 Alto e basso, altebasso, alterbass, or "up-and-down". 3 notes. Played harmony to the trumpet above it. 4 Sonata, quinta, principale. This became the modern standard trumpet, with a wide range of low and high notes. In this era it had between four and six notes and created a melody. 5 Clarin, claretta, claron, clarion. High ranging part, flourishes and some melody parts above the quinta. The highest notes were hard to play. When these notes were by a shorter nafir (they could be long), the effect was not musical but "excruciating". In the 16th century, a clareta or "sopranoor clarino" in C was tuned to the 8th partial, c" or c5, and might reach as high as the 13th partial. In a 5-trumpet ensemble of trumpets as long as 8 feet, it would be paired with a standard trumpet. The long trumpet was tuned an octave lower, and called sonata, quinta or principale). The other
