Musical instruments are generally divided into 6 broad categories which are: 1) Brass 2) Percussion 3) Key board 4) Guitars 5) Bowed Strings 6) Woodwind This article is going to give you a brief description of these above mentioned categories and the instruments falling within each category. 1) BRASS Brass instruments are generally those which we can play by blowing in them. These instruments further include a)- Trumpet: this instrument is considered as one of the most old instruments. It has series of valves on the top of it and is played horizontally. Different pitches are created by opening and closing of the valves on it. a)- Trombone: This instrument is operated without using either the key system or the valves. This instrument is elliptical in shape and can be easily recognized by its elongated size ending at a conical shaped bore. b)- French Horn: this instrument was anciently used by using the horns of animals and got its name from there. The shape it is available now-a-days is quite complex having a tube in a round shape which ends at a conical shape bore. It has centrally set valves to alter pitch. c)- Tuba: It resembles french horn and the difference is that instead of circular tube shape, it is in oval shape. The valves are placed at the center of this instrument on the oval shaped tube. 2) PERCUSSION These are the instruments where you strike a resonating surface either with the help of stick or your hand. These can be further divided into the following sub-categories: a)- Tuned instruments include vibraphone, xylophone, timpani, tubular bells, pianos, etc. b)- Indefinite pitch instruments include various types of drums, whip, triangle etc. 3) KEYBOARD INSTRUMENTS As the name suggests, key board instruments are those that are operated with the help of a keyboard. These are classified as a)- Electronic (which are operated through electronics) b)- Striking (where we hit the strings actually) c)-Aerated (where activation of notes takes place by propelled air mechanically) and d)- Plucking (where strings are plucked e.g. spinet) 4) GUITARS These are traditionally 6 stringed instruments and are played usually with fingers. These have got various advancements ranging from classical guitars to electric guitars which use amplifiers to amplify the sound. 5) BOWED STRINGS This family of bowed stringed instruments include the violins, the cellos, double basses and the viloas. These instruments can be played either by plucking the strings or can be played with the help of bows. 6) WOOD WIND The instruments falling within this category include flute, oboe, clarinet and bassoon. These are normally long horizontal instruments and are played by blowing air with your mouth. These are normally made of wood. These are the six categories of musical instruments which have instruments ranging from the classical types to most modern electrical instruments. One fine example is electric guitar which is an advanced form of classical guitar. Any instrument you find and play will fall in any of these above categories.
