The drop is a unit of measure of volume, the amount dispensed as one drop from a dropper. It is often used in giving quantities of liquid drugs to patients, and occasionally in cooking.
The volume of a drop is not well-defined: it depends on the device and technique used to produce the drop, on the strength of the gravitational field, and on the density and the surface tension of the liquid.[1]
There are several exact definitions of a "drop":
- the "metric" drop, 1/20 mL (50 μL)[2]
- in medicine, IV drips deliver 10, 15, or 20 drops per mL for macrodrip, 60 per mL for microdrip[3]
- an informal (and incorrect) synonym for minim, the smallest unit of fluid measure in the Apothecaries' systems of the United States customary units, Imperial units, and pre-1824 English units equal to 1/60 of a fluid dram or 1/480 of a fluid ounce
- prior to the adoption of the minim in the early 19th century, the smallest unit of fluid measure in the Apothecaries' systems of the United States customary units and pre-1824 English units, inexact, but presumed to be equal to 1/60 of a fluid dram or 1/480 of a fluid ounce
History [link]
In the first decade of the 19th century, the minim, the smallest unit of Apothecary Measure, was promoted by the pharmaceutical and medical establishments as an alternative to the drop.[4] It was noted that the size of a drop can vary considerably depending on the viscosity and specific gravity of the fluid, as well as the size and shape of the vessel from which it is poured. (At the time, surface tension was not well-understood.) The minim came with a set of procedures for ensuring accurate measurement, specifically, diluting powerful medicines that had previously been measured by the drop, then using a "minimometer" or "minim glass" (graduated pipette) with minim marks at regular intervals. The minim was defined as one 60th of a fluid dram or one 480th of a fluid ounce.[5] This is equal to about 61.6 μL (U.S.) or 59.2 μL (Britain).
Pharmacists have since moved to metric measurements, with a drop being rounded to exactly 0.05 mL (that is, 20 drops per milliliter). In hospitals, intravenous tubing is used to deliver medication in drops of various sizes ranging from 10 drops/mL to 60 drops/mL. A drop is abbreviated gtt, with gtts used for the plural. These abbreviations come from gutta, the Latin for drop.[6]

Drop (music)
A drop in popular music, especially electronic music styles, is a point in a music track where a switch of rhythm or bass line occurs and usually follows a recognizable build section and break.
The term "drop" comes from the composer or producer "dropping in" the primary rhythmic and foundational elements previously hinted at into the mix more or less at once. Related terms, typically describing certain types of drops, include "beat-up" (so named because it is a point where the producer brings up the foundational kick drum beat after having faded it down during a break or buildup) and "climax" (typically describing a single particularly striking drop heard late in the track).
Types
Many genres of EDM can have more than one drop during a track, especially if the song is built on a "dance-pop" verse/chorus with vocals; a drop of some kind is typically heard somewhere during each chorus as the high point of that verse/chorus cycle. Most genres, however, tend to emphasize a single drop as the beginning of the high point, or climax, of the entire track; in vocal subgenres this is typically the last repetition of the chorus, while in nonvocal genres it typically occurs in the last quarter of the track.
Overhand (boxing)
An overhand (or overcut or drop) is a semi-circular and vertical punch thrown with the rear hand. It is usually employed when the opponent is bobbing or slipping. The strategic utility of the drop relying on body weight can deliver a great deal of power.

Bass note
In music theory, the bass note of a chord or sonority is the lowest note played or notated. If there are multiple voices it is the note played or notated in the lowest voice. (the note furthest in the bass) While the bass note is often the root or fundamental of the chord, it does not have to be, and sometimes one of the other pitches of the chord will be found in the bass. See: inversion (music).
In pre-tonal theory (Early music), root notes were not considered and thus the bass was the most defining note of a sonority. See: thoroughbass. In pandiatonic chords the bass often does not determine the chord, as is always the case with a nonharmonic bass.
Bass (sound)
Bass (/ˈbeɪs/ BAYSS; Italian: basso, deep, low) describes tones of low frequency or range from 16-256 Hz (C0 to middle C4). In musical compositions, these are the lowest parts of the harmony. In choral music without instrumental accompaniment, the bass is supplied by adult male bass singers. In an orchestra, the bass lines are played by the double bass and cellos, bassoon and/or contrabassoon, low brass such as the tuba and bass trombone and the timpani (kettledrums). In many styles of traditional music such as Bluegrass, folk, and in styles such as Rockabilly and jazz, the bass role is filled by the upright bass. In most rock and pop bands and in jazz fusion groups, the bass role is filled by the electric bass. In some 20th and 21st century pop genres, such as 1980s pop and Electronic Dance Music, the bass role may be filled with a bass synthesizer.
Musical role
Played in a musical ensemble such an orchestra, such notes are frequently used to provide a counterpoint or counter-melody, in a harmonic context either to outline or juxtapose the progression of the chords, or with percussion to underline the rhythm. In popular music the bass part most often provides harmonic and rhythmic support, usually playing the root or fifth of the chord and stressing the strong beats. "The bass differs from other voices because of the particular role it plays in supporting and defining harmonic motion. It does so at levels ranging from immediate, chord-by-chord events to the larger harmonic organization of a entire work."
Busted (2004 Busted album)
Busted is a compilation album by British pop rock band Busted, released in the United States in October 2004. Ten of the twelve tracks had been released as singles in the United Kingdom, with "Falling for You" being included with the intention of its being released as the group's first single in the United States, and "Teenage Kicks" being included due to its popularity amongst British fans. The song is a cover of The Undertones' classic, first issued as the B-side of "Who's David?". This could allow the album to be viewed as the band's greatest hits. The album contains four tracks from their first album, also titled Busted and seven from the follow-up A Present for Everyone. The release of the album coincided with a documentary titled America or Busted, which chronicled the band's ill-fated attempts to break into the American market.
