Träblåsinstrumenten

Träblåsinstrumenten, or woodwind instruments, are a family of musical instruments that produce sound when a stream of air is directed against a sharp edge or through a reed, causing the air column within the instrument to vibrate. Despite the name, not all woodwind instruments are made of wood; modern examples often utilize metal, plastic, or other materials. The classification is based on the method of sound production.

The primary division within woodwinds is between instruments that use a single reed or a double reed, and those that produce sound by blowing across an edge, similar to a flute. Single-reed instruments, such as the clarinet and saxophone, use a reed attached to a mouthpiece. The vibration of this reed against the mouthpiece creates the sound. Double-reed instruments, like the oboe, bassoon, and English horn, employ two pieces of reed bound together. The player blows between these reeds, causing them to vibrate against each other.

Edge-blown instruments, exemplified by the flute and piccolo, do not use reeds. Instead, the player blows across a sharp edge, splitting the air stream and initiating vibration within the instrument's body. The pitch of woodwind instruments is altered by opening and closing keys and holes along the instrument's body. This changes the effective length of the vibrating air column, thus changing the fundamental frequency and producing different notes. Woodwind instruments are found in a wide array of musical genres, from classical orchestras and chamber ensembles to jazz bands and folk music.
