Musical Notes Live Wallpaper

Music notation systems have used letters of the alphabet for centuries. The 6th century philosopher Boethius is known to have used the first fifteen letters of the alphabet to signify the notes of the two-octave range that was in use at the time. Though it is not known whether this was his devising or common usage at the time, this is nonetheless called Boethian notation.

Following this, the system of repeating letters A-G in each octave was introduced, these being written as minuscules for the second octave (a-g) and double minuscules for the third (aa-gg). When the compass of used notes was extended down by one note, to a G, it was given the Greek G (Γ), gamma. (It is from this that the French word for scale, gamme is derived, and the English word gamut, from "Gamma-Ut", the lowest note in Medieval music notation.)

The remaining five notes of the chromatic scale (the black keys on a piano keyboard) were added gradually; the first being B, which was flattened in certain modes to avoid the dissonant tritone interval. This change was not always shown in notation, but when written, B♭ (B-flat) was written as a Latin, round "b", and B♮ (B-natural) a Gothic or "hard-edged" b. These evolved into the modern flat and natural symbols respectively. The sharp symbol arose from a barred b, called the "cancelled b".

In parts of Europe, including Germany, the Czech Republic, Poland, Hungary, Norway, Finland, and Russia, the natural symbol transformed into the letter H (possibly for hart, German for hard): in German music notation, H is B♮ (B-natural) and B is B♭ (B-flat). Occasionally, music written in German for international use will use H for B-natural and Bb for B-flat (with a modern-script lowercase b instead of a flat sign). Since a Bes or B♭ in Northern Europe (i.e. a Belsewhere) is both rare and unorthodox (more likely to be expressed as Heses), it is generally clear what this notation means.

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.
