Ca.

Circa? Often dates will be preceded with a "c." or a "ca." These are abbreviations of the Latin word "circa" which means around, or approximately. We use this before a date to indicate that we do not know exactly when something happened, so c. 400 B.C.E. means approximately 400 years Before the Common Era.

2. A term used to indicate tempo in metronome markings. So, "ca. =66" would indicate that the tempo should be "around" 66 beats per minute. This is a slow tempo in the range of adagio, lento or larghetto.

Sometimes the letter “C” (meaning common time) will be used in place of 4/4. Both C and 4/4 indicate that there are four quarter note beats in each measure. For 2/4 and 3/4, there are two and three quarter note beats per measure, respectively.

ca. means "circa", meaning "around". This tempo marking then says that the minim -- the half note -- is around 76-80, where 76-80 is a range of beats per minute.

Alla breve [alla ˈbrɛːve] – also known as cut time or cut common time – is a musical meter notated by the time signature symbol (a C with a vertical line through it), which is the equivalent of 2. 2. . The term is Italian for "on the breve", originally meaning that the beat was counted on the breve.

The "C" after the clef in place of the time signature stands for "Common Time," and it is shorthand for 4/4 time. If you see a "C" with a vertical line through it, that stands for "Cut Time," and it is shorthand for 2/2 time.

C major (or the key of C) is a major scale based on C, consisting of the pitches C, D, E, F, G, A, and B. C major is one of the most common keys used in music. Its key signature has no flats or sharps. Its relative minor is A minor and its parallel minor is C minor.

C = clean, which is fairly typical of greatest hits compilations, as they usually include the "radio" edit of the song. The explicit version is usually found only on the original-issue album.

In order to maintain a normal calcium level, the body uses hormones to regulate blood calcium levels. The normal regulation of calcium in our blood stream is similar to the way a thermostat works. The body is set to have a normal amount of calcium (somewhere between 8.6 to 10.3 mg/dL).

Too much calcium in your blood can weaken your bones, create kidney stones, and interfere with how your heart and brain work.
