Bore (wind instruments)In music, the bore of a wind instrument (including woodwind and brass) is its interior chamber. This defines a flow path through which air travels, which is set into vibration to produce sounds. The shape of the bore has a strong influence on the instrument's timbre. The cone and the cylinder are the two idealized shapes used to describe the bores of wind instruments. Other shapes are not generally used, as they tend to produce dissonant, anharmonic overtones and an unmusical sound.
HarmonicA harmonic is a sinusoidal wave with a frequency that is a positive integer multiple of the fundamental frequency of a periodic signal. The fundamental frequency is also called the 1st harmonic, the other harmonics are known as higher harmonics. As all harmonics are periodic at the fundamental frequency, the sum of harmonics is also periodic at that frequency. The set of harmonics forms a harmonic series. The term is employed in various disciplines, including music, physics, acoustics, electronic power transmission, radio technology, and other fields.
TrumpetThe trumpet is a brass instrument commonly used in classical and jazz ensembles. The trumpet group ranges from the piccolo trumpet—with the highest register in the brass family—to the bass trumpet, pitched one octave below the standard B or C trumpet. Trumpet-like instruments have historically been used as signaling devices in battle or hunting, with examples dating back to at least 2000 BC. They began to be used as musical instruments only in the late 14th or early 15th century.
The Rite of SpringThe Rite of Spring (Le Sacre du printemps) is a ballet and orchestral concert work by the Russian composer Igor Stravinsky. It was written for the 1913 Paris season of Sergei Diaghilev's Ballets Russes company; the original choreography was by Vaslav Nijinsky with stage designs and costumes by Nicholas Roerich. When first performed at the Théâtre des Champs-Élysées on 29 May 1913, the avant-garde nature of the music and choreography caused a sensation.
Acoustic resonanceAcoustic resonance is a phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration (its resonance frequencies). The term "acoustic resonance" is sometimes used to narrow mechanical resonance to the frequency range of human hearing, but since acoustics is defined in general terms concerning vibrational waves in matter, acoustic resonance can occur at frequencies outside the range of human hearing.
Contrabass clarinetThe contrabass clarinet (also pedal clarinet, after the pedals of pipe organs) and contra-alto clarinet are the two largest members of the clarinet family that are in common usage. Modern contrabass clarinets are transposing instruments pitched in B♭, sounding two octaves lower than the common B♭ soprano clarinet and one octave below the bass clarinet. Some contrabass clarinet models have extra keys to extend the range down to low written E♭_3, D_3 or C_3. This gives a tessitura written range, notated in treble clef, of C_3 – F_6, which sounds B♭_0 – E♭_4.
Brass bandA brass band is a musical ensemble generally consisting entirely of brass instruments, most often with a percussion section. Ensembles that include brass and woodwind instruments can in certain traditions also be termed brass bands (particularly in the context of New Orleans and Japan–style brass bands), but may be more correctly termed military bands, concert bands, or "brass and reed" bands. Balkan Brass Band Balkan-style Brass Bands (Труба, trumpet) play a distinctive style of music originating in 19th century Balkans.
Drum and bugle corps (modern)A modern drum and bugle corps is a musical marching unit consisting of brass instruments, percussion instruments, electronic instruments, and color guard. Typically operating as independent non-profit organizations, corps perform in competitions, parades, festivals, and other civic functions. Participants of all ages are represented within the corps activity, but the majority are between the ages of 13 and 22 and are members of corps within Drum Corps International or Drum Corps Associates.
March (music)A march, as a musical genre, is a piece of music with a strong regular rhythm which in origin was expressly written for marching to and most frequently performed by a military band. In mood, marches range from the moving death march in Wagner's Götterdämmerung to the brisk military marches of John Philip Sousa and the martial hymns of the late 19th century. Examples of the varied use of the march can be found in Beethoven's Eroica Symphony, in the Marches Militaires of Franz Schubert, in the Marche funèbre in Chopin's Sonata in B flat minor, the "Jäger March" in the Op.
Petrushka (ballet)Petrushka (Pétrouchka; Петрушка) is a ballet by Russian composer Igor Stravinsky. It was written for the 1911 Paris season of Sergei Diaghilev's Ballets Russes company; the original choreography was by Michel Fokine and stage designs and costumes by Alexandre Benois, who assisted Stravinsky with the libretto. The ballet premiered at the Théâtre du Châtelet on 13 June 1911 with Vaslav Nijinsky as Petrushka, Tamara Karsavina as the lead ballerina, Alexander Orlov as the Moor, and Enrico Cecchetti the charlatan.
