Membranes contain large amounts of lipids, which are notoriously hydrophobic (water and oil don't mix). The membrane-spanning regions of membrane proteins are typically alpha helices, made of hydrophobic amino acids.
Florence, for example, hosted a brilliant period of musico-theatrical innovation at the dawn of the seventeenth century that led to the flowering of early opera. Rome continued to influence sacred music and for a time became an important center of opera, several types of vocal chamber music, and instrumental music. Venice, a leading musical city throughout the seventeenth century, nurtured the development of opera, as did Naples in the eighteenth century.
Baroque music is a style of Western art music composed from approximately 1600 to 1750. This era followed after the Renaissance music era, and was followed in turn by the Classical era. Baroque music forms a major portion of the classical music canon, being widely studied, performed, and listened to.
