And using that idea for how someone makes you feel, instead of those butterflies, it makes your heart beat really, really fast." [2] "Hummingbird Heartbeat" is a 1980s-styled hard rock song that contains a mixture of elements from rock and electronica. [3] [4] The song encompasses electric guitars, a piano, and synthesizers in its production ...
They are known as hummingbirds because of the humming sound created by their beating wings, which flap at high frequencies audible to other birds and humans. They hover at rapid wing-flapping rates, which vary from around 12 beats per second in the largest species to 80 per second in small hummingbirds.
A metronome (from Ancient Greek μέτρον (métron) 'measure' and νόμος (nómos) 'law') is a device that produces an audible click or other sound at a uniform interval that can be set by the user, typically in beats per minute (BPM). Metronomes may also include synchronized visual motion, such as a swinging pendulum or a blinking light.
For example, a tempo of 60 beats per minute signifies one beat per second, while a tempo of 120 beats per minute is twice as rapid, signifying two beats every second. The note value of a beat will typically be that indicated by the denominator of the time signature. For instance, in 4 4 time, the beat will be a crotchet, or quarter note.
If a pulse becomes too fast it would become a drone; one that is too slow would be perceived as unconnected sounds. [2] When the period of any continuous beat is faster than 8–10 per second or slower than 1 per 1.5–2 seconds, it cannot be perceived as such. [2] "Musical" pulses are generally specified in the range 40–240 beats per minute.
The giant hummingbird hovers at an average of 15 wing beats per second, a slow rate for a hummingbird. [14] Its resting heart rate is 300 beats per minute, with a peak rate in flight of 1020 beats per minute. [14] Energy requirements for hummingbirds do not scale evenly with size increases, meaning a larger bird such as giant hummingbird ...
Hummingbirds have one of the highest metabolic rates of any animal, with heart rates up to 1260 beats per minute, breathing rate of about 250 breaths per minute even at rest, and oxygen consumption of about 4 ml oxygen/g/hour at rest. [26]
As defined by the basic definition (4 beats per measure/bar), allegro is defined as fast, quick, and bright, meaning a tempo below 120 bpm isn't really defined as fast (though 112 bpm is moderately fast), and 120 bpm means 2 bps (beats per second), which makes it the reliable threshold for allegro. After all, 120 bpm = 30 measures/bars per minute.
