The Dieze is a short river in North Brabant, the Netherlands, tributary of the Meuse. It is formed by the confluence of the rivers Aa and Dommel in 's-Hertogenbosch. The part of the Dieze in the centre of 's-Hertogenbosch is called "Binnendieze": a partly covered network of canals. The Dieze flows into the Meuse near Hedel.

In music, sharp, dièse (from French), or diesis (from Greek) means higher in pitch. More specifically, in musical notation, sharp means "higher in pitch by a semitone (half step)," and has an associated sharp symbol, , which may be found in key signatures or as an accidental. Sharp is contrasted with flat, which refers to a lowering of pitch. Intonation may be flat, sharp, or both, successively or simultaneously.
