Home espresso machines are now easy to operate and affordable, too. Plus, they no longer require a lot of space, with some models being wholly hand-held, even! Some coffee machines claim to incorporate an espresso maker as well, but nothing beats a dedicated machine when you want espresso that’s authentic.

The matter of authenticity is increasingly open to debate, on the other hand, in a world where all types of coffee are being served up with a wide variety of syrups, creams, spices, and flavor extracts. First invented in 1901 in Milan in order to hasten up the brewing process, espresso means “fast” in Italian but ever-rising popularity has seen any number of steps added along the way: espresso affogato is served over ice cream, while bombón comes with condensed milk; corretto espresso contains liquor like brandy even as espresso con hielo contains two ice cubes.

Naturally, that’s what makes caffè espresso so popular, its sheer variety. In Italy, where it all started, southerners prefer it dark while northerners have it light. Variety is the name of the game when it comes to espresso coffee. Any kind of bean of any kind of roast level may be brewed espresso, or fast, through an espresso machine. This convenience is important as well, even though special espresso machines are necessary (but then, again, it is fast). Espresso is surely also popular because it does, after all, present such a concentration of caffeine!

But the growth of espresso coffee has a fittingly wide range of causes, and one of the most significant is the rise of urbanization, where espresso bars became another venue for the kind of socializing previously found in town squares. In the United States, espresso seems to have really taken off with the proliferation of chain coffee houses, while in Great Britain youth felt more welcome at cafes than at pubs.

Today’s windchimes are said to be descended from ancient Indian wind bells, which were cherished in China as decorations for pagodas and other buildings needing to scare away evil spirits. Japan developed glass wind bells, and wind chimes have long been associated with good luck in most of Asia, frequently placed according to the principles of geomancy such as feng shui.

Wind chimes discovered inside the United States have a tendency to be made out of wood or some kind of metal. They also have a tendency to be tubular in shape, though much more fanciful designs aren’t uncommon. Sounds created by wind chimes are not tunable and are just about entirely dependent on their construction – in particular the primary material. A typical wind chime generates sounds ranging from brightly tinkling to dull thudding.

These sounds are technically called inharmonic spectra, though sometimes very modest manipulation may possibly be achieved through such variables as altering the height of their placement. Audial frequencies are determined by a wind chime’s dimensions.

Individuals usually hang wind chimes right by the door in order to announce the presence of visitors. They are also used simply as decoration, and are particularly enjoyable to those who like the singing of birds. While of ancient pedigree, the 21st Century wind chime is getting a technological makeover in the form of windless wind chimes, which rely on solar power instead of the wind. In this way, when the air is calm one can still enjoy the relaxing notes!

No introduction to wind chimes would be complete without mentioning their use in musical performances. While not actual instruments as such, the sounds they produce, particularly under what manipulation can be managed, have been found useful to both classical and rock music – for instance, David Sitek of the band TV on the Radio often hangs a wind chime towards the end of his guitar.
