Octave In music, an octave (Latin: octavus : eighth) or perfect octave is the interval between one musical pitch and another with half or double its frequency. It is defined by ANSI as the unit of frequency level when the base of the logarithm is two.or example, if one note has a frequency of 440 Hz, the note an octave above it is at 880 Hz, and the note an octave below is at 220 Hz.

OCTAVE Part of the Network security glossary: OCTAVE (Operationally Critical Threat, Asset, and Vulnerability Evaluation) is a security framework for determining risk level and planning defenses against cyber assaults.CTAVE is designed to leverage the experience and expertise of people within the organization. The first step is to construct profiles of threats based on the relative risk that they pose. The process goes on to conduct a vulnerability assessment specific to the organization.

- Such a distance is called interval. An octave is the interval between two sounds one of which has twice the frequency of the other. We devide octave into 12 semitones. In our terms, one semitone = 1.05946... (basically the 12th root of 2).

Definitions &Translations In music, an octave or perfect octave is the interval between one musical pitch and another with half or double its frequency. The octave relationship is a natural phenomenon that has been referred to as the basic miracle of music, the use of which is common in most musical systems.

Octave band Analyzing a source on a frequency by frequency basis is possible but time consuming. The whole frequency range is divided into set of frequencies called bands.Each band covers a specific range of frequencies. For this reason, a scale of octave bands and one-third octave bands has been developed.nalyzing a source on a frequency by frequency basis is possible but time consuming.

- Each number listed above is doubled to create the next number. Each of the numbers above are the note C in the range of scales, with e ach being the beginning or end of an octave in the scale.The octave of tuning forks in this set is MIDDLE C (256 hz) through the next higher octave C (512 hz).he Harmonic Spectrum Set is a complete octave of 8 tuning forks (C,D,E,F,G,A,B,C) derived from Pythagorean Mathematics. This set is based on the the geometric sequence of numbers 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096.

Music Theory: What is an octave? The A an octave higher is 880 Hz, and the A an octave lower is 220 Hz. Any note with the frequency 2^n * 440 will be an A. It's a central mystery of human cognition why we hear pitches related by powers of two as being the same note.

What is the highness or lowness of sound? Pitch is a term used to refer to the height or lowness of a sound. The pitch of a sound is determined by the frequency of the sound waves. A higher pitch has a higher frequency. The noted called A that is the first A above middle C is often used as a note for tuning instruments to match each other, and has the frequency of 440Hz.

Opera Voices The soprano is the highest female voice type and they often take the leading female role. The vocal range for an operatic soprano is roughly from middle C up to the C two octaves above, though plenty of music particularly for coloratura sopranos ascends even further. Sopranos are split into five major categories: Coloratura

shrill shrill A shrill sound is high pitched and sharp, like the squeak of the mouse in your cupboard or the sound of your “eek” when you hear it. Closer to a shriek than a trill, a shrill tone is one that might make you cover your ears, usually because the tone is so high and sharp. A high pitched voice, a classroom of excited first graders, or the sound of chalk scraping the board can all be shrill, as can a color or light that looks as sharp and intense as a shrill tone sounds.

Octave An octave is the distance between two musical notes that have the same letter name. If a musician sings or plays a scale (‘do-re-mi-fa-sol-la-ti-do’) the first and last ‘doh’ are an octave apart. It is called an ‘octave’ because there are eight notes in a scale (‘octo’ is Latin for ‘eight’). If a musician sings or plays the first two notes of the song “Somewhere over the rainbow” (i.e. the word ‘Somewhere’) these two notes are an octave apart.

Music for Kids So the octave below in frequency would be the 3rd and the octave above in frequency would be the 5th. Each note in an octave is twice the pitch or frequency of the same note in the octave below. For example, an A in the 4th octave, called A4, is 440Hz and an A in the 5th octave, called A5 is 880Hz. The other important part of a musical note (besides pitch) is the duration. This is the time that the note is held or played. It is important in music that notes are played in time and rhythm.

Music Theory/Scales and Intervals Simple intervals are defined as those intervals that are one octave or less apart. Intervals are usually named according to the relationship of the higher note to the lower note in the major scale, though they also have alternative names depending upon the spelling of the particular notes on the page of music.

Harmonic A harmonic is any member of the harmonic series, the divergent infinite series. Its name derives from the concept of overtones, or harmonics in musical instruments: the wavelengths of the overtones of a vibrating string or a column of air (as with a tuba) are derived from the string's (or air column's) fundamental wavelength.

- In terms of intervals on the scale, we hear a base tone, its octave (eight notes up), then a note that is a twelfth up, i.e. a perfect fifth above the octave above the starting pitch, then a note two octaves up from the starting pitch, then one that is a major third above that, and on and on.

Octave For example, if one note has a frequency of 440 Hz, the note an octave above it is at 880 Hz, and the note an octave below is at 220 Hz.The ratio of frequencies of two notes an octave apart is therefore 2:1.or example, if one note has a frequency of 440 Hz, the note an octave above it is at 880 Hz, and the note an octave below is at 220 Hz.

Tech Stuff - Frequency Ranges Each standard uses what is called an equal tempered interval, that is, each note is related the next one by an equal amount. Each octave is comprised of 12 semi-tones (C, C#, D, D#, E, F, F#, G, G#, A, A#, B). Thus, the even tempered interval is the 12th root of 2 (12√2).
