Music.

Drum's

Percussion instruments can be divided into three main categories: idiophones which when played give out their own natural sound, membranophones, which depend for their sound on a membrane stretched over a resonator, and chordophones, involving struck strings.
Guitar's

There are many different types of guitars, falling into different categories so it is important you know the difference between them, and the benefits, when starting out on your guitar playing journeys. It is also important to understand the difference between playing styles and guitar types.
Synthesizer's

A sound synthesizer (often abbreviated as "synthesizer" or "synth") is an electronic instrument capable of producing a wide range of sounds. Synthesizers may either imitate other instruments ("imitative synthesis") or generate new timbres. They can be played (controlled) via a variety of different input devices (including keyboards, music sequencers and instrument controllers).
