In the early Baroque, these melodic embellishments that had been improvised in the Renaissance began to be incorporated into compositions as standardized melodic gestures. With the Baroque's emphasis on a soloist as virtuoso, the range of pitches and characteristic techniques formerly found only in virtuosic improvisation, as well as the first dynamic markings, were now written as the expected standard. On the other hand, some of the instrumental genres listed above, such as the prelude, toccata, and intonation, were improvisation-based to begin with. Even in the early sixteenth century, these genres were truly, idiomatically instrumental; they could not be adapted for voices because they were not composed in a consistent polyphonic style.
