That would be a melody. You may be thinking of 'motif'.
A musical pattern formed by a series of notes is a scale. The type of scale is dependent on the pattern

it means that they could tell when pitches come together what sounds good an what does not co ordinate it means they are good in detecting musical errors an good in listening with good constructive criticism

You might be thinking of 'white noise' except that white noise isn't really a random mix of pitches. I believe it is a deliberate mix of a very wide range of pitches. White noise is about as nonmusical as complete silence, but then again silence is not entirely nonmusical. I wouldn't enjoy a steady diet of white noise, but there are some experimental musics that incorporate it as an element.
Typically, when two or more pitches are sounded together, we identify the sound as "harmony". Depending on the character of this harmony, we can further describe the sound as "consonant" (meaning, "sounding good together"), or "dissonant". Consonant harmonies typically consist of the perfect intervals (unisons, octaves, fourths, and fifths), as well as thirds and sixths (major and minor). Dissonant intervals range from strong dissonances (such as the minor second and major seventh, as well as the augmented fourth), to lesser dissonances such as the minor seventh.

Sequencing means groups of notes that are put together in a sequence. This usually means something that is repetitive. An example could be c d e f g this is a sequence.it's a group of notes that's round about near to each other.
The musical staff was invented because it would be easier to figure out the different pitches and either it was the bass clef or the treble clef.
Yes, the octaves are the same notes but in varying pitches.

Boomwhackers are light weight, hollow plastic tubes that come in different colors that are tuned to musical pitches by length. Boomwhackers are musical instruments in the percussion family.
Yes, it does! No, a pentatonic scale has five notes.
you blow in the double reed, they vibrate, which creates sound, the air travels through the instrument and creates different notes/pitches based on the keys that are pressed down
Yes. Timpani drums can be tuned to play different pitches. Some musical pieces even require that the timpani be retuned during the piece to play a separate pitch.
Isorhythm (from the Greek for "the same rhythm") is a musical technique that arranges a fixed pattern of pitches with a repeating rhythmic pattern.
This is a pretty broad question. It really depends on what era of music we are talking about but overall I'd say using different instrumentation creates a great variety of sounds for composers and using a wide variety of tempos and pitches keeps it interesting.
