Tonguing is a technique used with wind instruments to enunciate notes using the tongue on the palate or the reed or mouthpiece. A silent "tee" [2] is made when the tongue strikes the reed or roof of the mouth causing a slight breach in the air flow through the instrument. If a more soft tone is desired, the syllable "da" (as in dou ble) is ...
B♭ alto — up a perfect fourth. A — up a major third. G — up a major second. E — down a minor second. E♭ — down a major second (used for horn on pitches with multiple sharps until Richard Strauss) D — down a minor third. C — down a perfect fourth. B♭ basso — down a perfect fifth.

Acoustic levitation is a method for suspending matter in air against gravity using acoustic radiation pressure from high intensity sound waves. [1][2] It works on the same principles as acoustic tweezers by harnessing acoustic radiation forces. However acoustic tweezers are generally small scale devices which operate in a fluid medium and are ...
Sonication can be used for the production of nanoparticles, such as nanoemulsions, [5] nanocrystals, liposomes and wax emulsions, as well as for wastewater purification, degassing, extraction of seaweed polysaccharides [1] and plant oil, extraction of anthocyanins and antioxidants, [6] production of biofuels, crude oil desulphurization, cell disruption, polymer and epoxy processing, adhesive ...
Conservation-restoration of bone, horn, and antler objects involves the processes by which the deterioration of objects either containing or made from bone, horn, and antler is contained and prevented. Their use has been documented throughout history in many societal groups as these materials are durable, plentiful, versatile, and naturally ...
Embouchure (English: / ˈɒmbuˌʃʊər / ⓘ) or lipping[1] is the use of the lips, facial muscles, tongue, and teeth in playing a wind instrument.

The following list of chemical purification methods should not be considered exhaustive. Affinity purification purifies proteins by retaining them on a column through their affinity to antibodies, enzymes, or receptors that have been immobilised on the column. Filtration is a mechanical method to separate solids from liquids or gases by passing ...
Hand-stopping. Hand-stopping is a technique by which a natural horn or a natural trumpet can be made to produce notes outside of its normal harmonic series. By inserting the hand, cupped, into the bell, the player can reduce the pitch of a note by a semitone or more. This, combined with the use of crooks changing the key of the instrument ...
