The term glissando (also glissato, glisscato, glissicando; "slide" from the French glisser derived ) refers to the continuous music (moving ) changing the pitch.
Instrument -specific subdivision
Glissandi ( " true" glissando ) are over a larger interval of time only possible with musical instruments that are not fixed to particular sounds. These include
- String instruments without frets
- Guitar with the help of a Bottlenecks
- Confederation lots representative of the read
- Ondes Martenot
The glissando with timpani is a widely used technique in modern percussion composition. The bass drum is played while the vocal pedal is depressed.
For other woodwind and brass wind instruments, the pitch is usually pre-defined by a specific extension of the wind tunnel or handle holes. Changes in pitch are possible to a limited extent, such as the clarinet by partially closed handle holes and change in the approach. These instruments include
Instruments with predefined pitches that do not influence the pitch hindsight is possible, can only imitate a glissando. In addition to chromatic glissandi ( in which the tones are run in semitone steps) there is the possibility of a diatonic glissando (only sub- keys, Tonvorrat cdefgah ) and a pentatonic glissandos (only the black keys, Tonvorrat cis- It - F #- G # -B) are representative of these instruments
- Keyboard Instruments such as piano
A special way of glissandos offers the double -action pedal harp. Through various pedal positions to glissandi can play up Ais minor in every key of C flat major to C major and minor of As. In addition, whole-tone and pentatonic glissandos can be played. There is also the possibility of so-called " chord glissandos " to play: For this purpose the " disturbing", chord strange notes of a scale enharmonically changed. Example: As7 has the pedal position As- His- C -Dis - E Fis -Ges. Thus, for many seventh and ninth chords and diminished seventh chords all set. In modern literature, especially in jazz, there is yet another technique, the so-called " pedal glissando ". Here, a string is plucked and immediately thereafter entered as the pedal. The melodious sound increased almost continuously by a semitone.
The glissando is recorded by means of a shaft (No. 1) or straight line ( No. 2) between the initial and final sound.
The sequences 3 and 4 show the graphic notated versions of this glissandos, as they would be playable for example on a keyboard instrument. Number 3 is a diatonic and a chromatic glissando number 4. The absolutely precise notation of a glissando is not possible as a glissando itself is continuous, but notes describe discrete pitches. Mathematically, there is a glissando of infinite shades of infinitely short duration. Alternative ways of playing are 5, wherein the glissando is doubled at the octave, and 6, in which the " root notes " of glissandos other diatonic tones are added and taken a Akkordglissando arises.
In the piano notation, the scales can also tendered and glissando with the statement, gliss. , Or gl provided.
