The main difference between Clarinet and Oboe is that the Clarinet is a type of woodwind instrument and Oboe is a musical instrument of the woodwind family
The clarinet is a family of woodwind instruments. It has a single-reed mouthpiece, a straight, cylindrical tube with an almost cylindrical bore, and a flared bell. A person who plays a clarinet is called a clarinetist (sometimes spelled clarinettist).
While the similarity in sound between the earliest clarinets and the trumpet may hold a clue to its name, other factors may have been involved. During the Late Baroque era, composers such as Bach and Handel were making new demands on the skills of their trumpeters, who were often required to play difficult melodic passages in the high, or as it came to be called, clarion register. Since the trumpets of this time had no valves or pistons, melodic passages would often require the use of the highest part of the trumpet’s range, where the harmonics were close enough together to produce scales of adjacent notes as opposed to the gapped scales or arpeggios of the lower register. The trumpet parts that required this specialty were known by the term clarino and this in turn came to apply to the musicians themselves. It is probable that the term clarinet may stem from the diminutive version of the ‘clarion’ or ‘clarino’ and it has been suggested that clarino players may have helped themselves out by playing particularly difficult passages on these newly developed “mock trumpets”.Johann Christoph Denner is generally believed to have invented the clarinet in Germany around the year 1700 by adding a register key to the earlier chalumeau, usually in the key of C. Over time, additional keywork and airtight pads were added to improve the tone and playability.In modern times, the most popular clarinet is the B♭ clarinet. However, the clarinet in A, just a semitone lower, is regularly used in orchestral music. An orchestral clarinetist must own both a clarinet in A and B♭ since the repertoire is divided fairly evenly between the two. Since the middle of the 19th century the bass clarinet (nowadays invariably in B♭ but with extra keys to extend the register down a few notes) has become an essential addition to the orchestra. The clarinet family ranges from the (extremely rare) BBB♭ octo-contrabass to the A♭ piccolo clarinet. The clarinet has proved to be an exceptionally flexible instrument, used in the classical repertoire as in concert bands, military bands, marching bands, klezmer, jazz, and other styles.
The Oboe ( OH-boh) is a type of double reed woodwind instrument. Oboes are usually made of wood, but may also be made of synthetic materials, such as plastic or resin. The most common oboe plays in the treble or soprano range. A soprano oboe measures roughly 65 cm (25 1⁄2 in) long, with metal keys, a conical bore and a flared bell. Sound is produced by blowing into the reed at a sufficient air pressure, causing it to vibrate with the air column. The distinctive tone is versatile and has been described as “bright”. When the word oboe is used alone, it is generally taken to mean the treble instrument rather than other instruments of the family, such as the bass oboe, the cor anglais (English horn), or oboe d’amore
A musician who plays the oboe is called an oboist.
Today, the oboe is commonly used as orchestral or solo instrument in concert bands, orchestras, chamber music, film music, some genres of folk music, and is occasionally heard in jazz, rock, pop, and popular music.
A woodwind musical instrument that has a distinctive liquid tone whose characteristics vary among its three registers: chalumeau (low), clarion (medium), and altissimo (high).
A soprano and melody wind instrument in the modern orchestra and wind ensemble. It is a smaller instrument and generally made of grenadilla wood. It is a member of the double reed family.
