rü

Ré is the second note of the solfège scale in many musical traditions, corresponding to the pitch D. In movable-do systems the syllables do-re-mi-fa-sol-la-si designate scale degrees relative to the tonic; in fixed-do systems re always equals D. The note is written as ré in French notation and can occupy different octaves; its frequency depends on the octave and tuning standard (for example, D4 is about 293.66 Hz under A4 = 440 Hz).

The Île de Ré is a French island located off the Atlantic coast near La Rochelle in the Charente-Maritime department, Nouvelle-Aquitaine. It is connected to the mainland by a bridge, the Pont de Ré. The island is known for its long sandy beaches, salt flats, and oyster farming. It comprises several towns, including Saint-Martin-de-Ré and La Flotte, and is a popular destination for cycling and maritime leisure.

Historically, the island features coastal fortifications dating from the 17th century built to defend the Atlantic coast, notably at Saint-Martin-de-Ré and Fort La Prée, designed by Vauban-era engineers. Today Ré is a popular tourist destination, especially in summer, drawing visitors with its mild climate, bike routes, and seafood cuisine.
