The bass oboe or baritone oboe is a double reed instrument in the woodwind family. It is about twice the size of a regular (soprano) oboe and sounds an octave lower; it has a deep, full tone somewhat akin to that of its higher-pitched cousin, the English horn.
The oboe is a C woodwind with a base pitch tuned to C, while the cor anglais is an F woodwind with a base pitch tuned a perfect fifth lower, to F. How might the oboe and the cor anglais differ from one another structurally? There is a law that every doubling of the length of the pipe lowers the pitch by one octave.
Oboes (/ ˈ oʊ b oʊ / OH-boh) are a family of double reed woodwind instruments. The most common oboe plays in the treble or soprano range. Oboes are usually made of wood, but there are also oboes made of synthetic materials. A soprano oboe measures roughly 65 cm (25 1 ⁄ 2 in) long, with metal keys, a conical bore and a flared bell.
The oboe d'amore (pronounced [ˈɔːboe daˈmoːre]; Italian for "oboe of love"), less commonly hautbois d'amour, is a double reed woodwind musical instrument in the oboe family. Slightly larger than the oboe, it has a less assertive and a more tranquil and serene tone, and is considered the alto of the oboe family, between the oboe and the cor anglais, or English horn .
The oboe da caccia (pronounced [ˈɔːboe da ˈkattʃa]; literally "hunting oboe" in Italian), also sometimes referred to as an oboe da silva, is a double reed woodwind instrument in the oboe family, pitched a fifth below the oboe and used primarily in the Baroque period of European classical music.
The oboe as we know it today did not appear until about a century later, and that name did not come into common usage until the 18th century. In the context of the organ, the word hautbois seems to have originated in early 16th century France as a registration of mutations rather than as a single reed stop.
The members of the oboe family from top: heckelphone, bass oboe, cor anglais, oboe d'amore, regular oboe, and piccolo oboe The standard oboe has several siblings of various sizes and playing ranges. The most widely known and used today is the cor anglais, or English horn, the tenor (or alto) member of the family.
The piccolo oboe, also known as the piccoloboe and historically called an oboe musette, is the smallest and highest pitched member of the oboe family. Pitched in E♭ or F above the regular oboe, the piccolo oboe is a sopranino version of the oboe, comparable to the E♭ clarinet.
