Musical Instruments
In a world where the song of existence thrums through everything, musical instruments are vitally important! Or at the very least, they certainly provide entertainment and beauty for people from all places and walks of life. There are four basic types of instruments in Avaria: percussion, stringed, woodwind, and keyboard. This list is illustrative rather than exhaustive -- not all these instruments are currently coded into the game, and there are certainly many more whose time period and origin would find them a place in Avaria.
Percussion Instruments
These are the oldest of the musical instruments. They exist in two subtypes, idiophone (where sound is created primarily by the vibration of the instrument itself) and membranophone (where sound is created by means of a vibrating stretched membrane). There's no functional difference between the two in terms of mechanics, but the difference may help in imagining the instrument in question and how it works and sounds.
Woodwind Instruments
Not just made of wood, but also metal and bone. Woodwinds come in two primary subtypes, flutes (reedless instruments that create sound by vibrating the air across an opening) and reed instruments (where sound is created by vibrating a thin strip of material inside the instrument).
Stringed Instruments
These exist in immense variety, and are divided into two subtypes, plucked and bowed. Plucked instruments may require a pick or plectrum to play, or they may be played with the fingers alone. Bowed instruments (unsurprisingly) require a bow to play.
Keyboard Instruments
This is the most modern group of instruments, with most only having been devised in the last two hundred years or so. They are divided into two subtypes, the venerable aerophone (creating sound by forcing pressurized air through pipes, mediated by keys) and the new-fangled chordophones (creating sound by striking at or plucking strings, likewise mediated by keys).
