Fortified wine because he was inspired by a German wine flavoured with wormwood, an herb most famously used in distilling absinthe. However, wine flavoured with wormwood goes back to ancient Rome. The modern German word "Wermut" ("Wermuth" in the spelling of Carpano's time) means both "wormwood" and "vermouth". The herbs were originally used to mask raw flavours of cheaper wines, imparting a slightly medicinal "tonic" flavor. Vins doux naturels are lightly fortified wines typically made from white Muscat grapes or red Grenache grapes in the south of France. The production of vins doux naturels was perfected by Arnaud de Villeneuve at the
Additive synthesis derivative is divided by formula_28. This is the case whether the partial is harmonic or inharmonic and whether its frequency is constant or time-varying. In the most general form, the frequency of each non-harmonic partial is a non-negative function of time, formula_29, yielding "Additive synthesis" more broadly may mean sound synthesis techniques that sum simple elements to create more complex timbres, even when the elements are not sine waves. For example, F. Richard Moore listed additive synthesis as one of the "four basic categories" of sound synthesis alongside subtractive synthesis, nonlinear synthesis, and physical modeling. In this broad sense, pipe
