Si

In Anglophone countries, "si" was changed to "ti" by Sarah Glover in the nineteenth century so that every syllable might begin with a different letter (also freeing Si for later use as Sol-sharp). “Ti" is used in tonic sol-fa (and in the famed American show tune "Do-Re-Mi").

[Subito piano (abbreviated sub. p or sp) ("suddenly soft") indicates that the dynamics quickly, almost abruptly, lower the volume to approximately the p range. It is often purposefully used to subvert the listener's expectation and will signify an intimate expression.

In traditional Indian music, musical notes are called svaras and commonly represented using the seven notes, Sa, Re, Ga, Ma, Pa, Dha and Ni.

If you are in the key of C Major, “do” would be C, “re” would be D, and “mi” would be E, etc. Or if you are in the key of A Major, “do” is A, “re” is B, “mi” is C#. I hope that's super easy to understand so far.

Si (without an accent) is a conjunction that means 'if', whereas sí (with an accent) is either an adverb that means 'yes', or a pronoun that means 'oneself' – usually. Emphatic Exceptions. I say usually as their meaning can change if used in conjunction with other words to emphasize something.

In the 19th century, the English music educator Sarah Glover changed that si to ti, in order for the entire scale to be notated with the first letter of each syllable (sol had already called dibs on the letter “s”). Italians hold onto that si, but English-speaking countries usually sing ti.

Back in the 20th Century, the term EP stands for Extended Play Record. It referred to a type of vinyl record that was played at a different speed than the standard play records (SPs and LPs). The difference between EP and LP is that an LP is 'Long Playing' and generally has more than 8 tracks.

So the final order of the 12-note chromatic scale, going upwards, is C, C sharp/D flat, D, D sharp/E flat, E, F F sharp/G flat, G, G sharp/A flat, A, A sharp/B flat, and B (see image above).

The 8 Elements of Music are, in alphabetical order, Dynamics, Form, Harmony, Melody, Rhythm, Texture, Timbre and Tonality.

Western music typically uses 12 notes – C, D, E, F, G, A and B, plus five flats and equivalent sharps in between, which are: C sharp/D flat (they're the same note, just named differently depending on what key signature is being used), D sharp/E flat, F sharp/G flat, G sharp/A flat and A sharp/B flat.

A tetrad is a set of four notes in music theory. When these four notes form a tertian chord they are more specifically called a seventh chord, after the diatonic interval from the root of the chord to its fourth note (in root position close voicing).
