Lots of reasons. If i nock my guitar against a shelf while i am playing, it can mess up the tuning and i have to retune it. also, humidity makes wood expand, and dryness makes it shrink, forcing compensation. I happen to know the oragn at my church is thrown way out of tune when the temperature changes between winter/summer and the metal shrinks/expands. The difference in the expansion/contraction change sthe way the air vibrates, so we have to compensate for it. also instruments get banged around before performance, whoch also puts them out of tune.
any instrument, i started on flute
the harpsichord
It is a harpsichord, a baroque keyboard instrument that was very popular before the piano was invented.
The triangle is a percussion instrument and is in the shape of a triangle and is made from metal- this instrument is normally played with a beater to make diferent sounds which start and finish before the next sound is made. :)
Before playing a full set of pipes, you learn on a practice chanter. Strictly speaking, it isn't an instrument itself, just a modified part of the pipes themselves.
The explanation point is always before the question mark.
No. They had physics before Einstein came along. Einstein made contributions to physics.
Yes, physics is important for a pediatrician. It is important as medical schools require a year of physics before enrollment.
Physics existed long before Stephen Hawking.

Harpsichord was before the piano.
I think you should learn grammar before you try to leearn physics.
Lots of things are invented before the physics of the widget are understood. So engineering is often first, followed by physics. Consider the aeroplane.
Time to maturity is the amount of time left before an investment instrument can be exchanged for cash. If the instrument is withdrawn before maturity, there is will fines.
Dogs have keen senses and can often pick up on cues or signals that humans may not notice, such as the sound or smell of approaching animals. While it may appear psychic, it is more likely that your dog is reacting to subtle cues that precede the appearance of the cat or other animal.
The instrument that was necessary for Cell Theory to be developed is the microscope.
Newtonian physics, also called classical or pre-relativistic physics refer to the physics after Aristotelian physics and before the 1920s when the theory of relativity was formed. They distinctly differ from Aristotelian physics in that they cover the physics of motion, scientific method, describe contact and non-contact forces such as magnetism
