DescriptionThe trumpet is the musical instrument with the highest register in the brass family. Trumpets are among the oldest musical instruments, dating back to at least 1500 BC. They are played by blowing air through closed lips, producing a "buzzing" sound that starts a standing wave vibration in the air column inside the instrument. Since the late 15th century they have primarily been constructed of brass tubing, usually bent twice into a rounded oblong shape.
There are several types of trumpet; the most common is a transposing instrument pitched in B♭ with a tubing length of about 148 cm. Earlier trumpets did not have valves, but modern instruments generally have either three piston valves or, more rarely, three rotary valves. Each valve increases the length of tubing when engaged, thereby lowering the pitch.
The most common type is the B♭ trumpet, but low F, C, D, E♭, E, G and A trumpets are also available. The C trumpet is most common in American orchestral playing, where it is used alongside the B♭ trumpet. Its slightly smaller size gives it a brighter, lively sound. Because music written for early trumpets required the use of a different trumpet for each key — they did not have valves and therefore were not chromatic — and also because a player may choose to play a particular passage on a different trumpet from the one indicated on the written music, orchestra trumpet players are generally adept at transposing music at sight, sometimes playing music written for the B♭ trumpet on the C trumpet, and vice versa.
The standard trumpet range extends from the written F♯ immediately below Middle C up to about three octaves higher. Traditional trumpet repertoire rarely calls for notes beyond this range, and the fingering tables of most method books peak at the high C, two octaves above middle C. Several trumpeters have achieved fame for their proficiency in the extreme high register, among them Maynard Ferguson, Cat Anderson, Dizzy Gillespie and more recently Wayne Bergeron. It is also possible to produce pedal tones below the low F♯, which is a device commonly employed in contemporary repertoire for the instrument.
If you’re not sure what live wallpapers are, they’re a type of application that works on a mobile device using the Android operating system (like your device!). The application works as a wallpaper – providing the background image for the home screen—but also works as a conventional application since it can provide user-interaction with the touch screen (allowing the image to change dynamically, for example) and access other hardware and software features within the device (accelerometer, GPS, network access, etc.).
**Multiple backgrounds!** Switch up the background as often or as little as you like with user-configurable options.
**Power saving features!** This app uses much less power than typical live wallpapers. It will take a bit more power to operate than a normal wallpaper, but much, much less battery power than the average live wallpaper.
**Super easy to use!** Upon install the app will bring up the options menu and then immediately let you set the wallpaper. No hassle and easy to use!
**Translated to 35 languages!** Do you really, really want to learn Russian? We didn’t think so, but it’s available just in case, in any language your phone can display!
Please note that live wallpapers can’t be set automatically. We’ll bring you to the setup screen where you’ll select the live wallpaper. We’d love to do it automatically but Android doesn’t allow it.
