interval

 [in´ter-val]
the space between two objects or parts; the lapse of time between two events.
AA interval the interval between two consecutive atrial stimuli.
atrioventricular interval (AV interval)
2. in dual chamber pacing, the length of time between the sensed or paced atrial event and the next sensed or paced ventricular event, measured in milliseconds; called also atrioventricular or AV delay.
cardioarterial interval the time between the apical beat and arterial pulsation.
confidence interval an estimated statistical interval for a parameter, giving a range of values that may contain the parameter and the degree of confidence that it is in fact there.
coupling interval the distance between two linked events in the cardiac cycle.
His-ventricular (H-V) interval an interval of the electrogram of the bundle of His, measured from the earliest onset of the His potential to the onset of ventricular activation as recorded on eight of the intracardiac bipolar His bundle leads or any of the multiple surface ECG leads; it reflects conduction time through the His-Purkinje system.
lucid interval
1. a brief period of remission of symptoms in a psychosis.
2. a brief return to consciousness after loss of consciousness in head injury.
PA interval the interval from the onset of the P wave on the standard electrocardiogram (or from the atrial deflection on the high right atrial ECG) to the A wave on the His bundle ECG; it represents intra-atrial conduction time.
postsphygmic interval the short period (0.08 second) of ventricular diastole, after the sphygmic period, and lasting until the atrioventricular valves open.
P–R interval in electrocardiography, the time between the onset of the P wave (atrial activity) and the QRS complex (ventricular activity).
presphygmic interval the first phase of ventricular systole, being the period (0.04–0.06 second) immediately after closure of the atrioventricular valves and lasting until the semilunar valves open.
QRST interval (Q–T interval) in the electrocardiogram, the length of time between ventricular depolarization (the Q wave) and repolarization (the T wave); it begins with the onset of the QRS complex and ends with the end of the T wave.
VA interval [ventricular-atrial interval] the interval between a ventricular stimulus and the succeeding atrial stimulus; it is equal to the AA interval minus the atrioventricular interval.

In both cases, the intervallic makeup of the pitch field lends a particular coloration to the music based on it.
By calculating the intervallic values through the geometrical proportional mean and the subdivision of the syntonic comma, he presents a table in which the string is hypothetically divided into 10,000,000 parts (pp.192-5).
It is difficult to see, however, how Lehr's intervallic tabulations, which make no allowances for rhythm, dynamics or phrasing, avoid differentiation on the basis of voice-leading considerations (neighbour- or passing-note patterns), harmonic context or dramatic situation, and are divorced from historical notions of affect, are anything more than a self-reflexive record of mechanical calculation.
Despite its gradual evolution out of treatises written in diverse languages, Farsi and Greek as well as Arabic, today 'maqam' (italicized as a technical term) applies unambiguously to a definitive system of intervallic relations among tones which differs from a key.
(25)Of the examples given, 15:10, 30:20; 12:9, 40:30, only 12:9 is of musical interest, being part of the intervallic formula 12:9:8:6.
From the folky lyrics and chiming guitars of the Beatles and Byrds to Led Zeppelin drum-bashing and Rolling Stones raunch, from looping Motown-inspired bass lines to flat-out punk-fired raves, from heartthrob vocals a la Patsy Cline and Duane Eddy-style twanging to throaty Booker T-ish organ sounds and the sudden intervallic leaps of Little Feat, the Palominos graps a mind-boggling number of musical bits in their teeth, and taken them to places they might never have gone.
Prereading--surveying for an overview (intervallic movement and so on)
Schoenberg illustrates this concept by showing antecedent phrases that are inadequate--some do not invert into their complement and others are ruled out for lacking intervallic variety, having too many leaps, or other such shortcomings of a traditional melody.
As advertised, the piece is cast in two movements of similar character, and is intended for "advanced performers." The technical demands for both parts include some challenging intervallic writing and some harmonic elements that are occasionally hard to follow.
The pedal point harmonies are always comprised of notes from the mode and their intervallic range is always that of a major seventh.
Rhythm refers to "explicit divisions of time or space into intervallic time systems, recurrent and often (but not always) characterized by periodicity" (Thaut, 2005, p.
Whitesell notices a shift from "linear to painterly" melodic thinking from Mitchell's first to second style periods, contrasting the "chiseled intervallic designs in fairly precise rhythmic coordination with accompanimental figures" of the former with the "more plastic contour" of the latter, which allows "for a lot of give in its alignment with the background" (24).
