Pitch is quantified relative to both high and low. Scales or other phrases performed in a range where two notes are separated by an octave. Some instruments with a range of about two octaves will designate a note as "high" or "low" in order to distinguish it from the other note of the same name. Vocalists’ ranges are frequently characterized as "high" and "low" because it’s clear which note is meant if you know the singer’s gender and/or general voice type. Referring to strings that are different by one octave; a guitar, for instance, has two E strings: a low E and a high E. Referring to musical instruments that are frequently tuned both standard and re-entrant. Generally speaking, this naming convention can be used instead of always using scientific pitch classification or any other system when it is clear what note is being referred to in context.
IN CASE IT WAS NOT EXTREMELY CLEAR, "HIGH" REFERS TO THE NOTE WITH A HIGHER FREQUENCY. A "LOW" FREQUENCY IS DEFINED AS SUCH.
If the piano is being used as an example, anything on the keyboard to the right of middle C is regarded as a "high" note (pitch), and anything to the left of middle C is regarded as a "low" note (pitch). "Low C" usually refers to a C note that is below (or to the left) of middle C on the keyboard, whereas "High C" usually refers to any C note on the keyboard that is to the right of middle C.
We’ll learn what low and high notes are next.
The range of sounds that can be perceived by the human ear is extremely great and includes very low and very high notes. The so-called CLEFS contains the solution: the higher note treble clef and the low note bass clef. While the staff’s five lines and four spaces are already quite effective in visually representing tones, we also have a way to represent notes that are higher or lower than what the staff would typically permit.
Let’s discuss what a high C note is.
The first note and semitone of the C major scale is C, or DO. The actual frequency has been determined by previous pitch norms. In scientific pitch notation, middle C (the fourth C key from left on a typical 88-key piano keyboard) is denoted as C4. A Western concert flute player might refer to C4 as Low C. The soprano’s C6 or the tenor’s C5 are referred to as "High C" in vocal music.
