Questions tagged [octave]

An octave or perfect octave is the interval between one musical pitch and another with half or double its frequency.

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. 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". It may be derived from the harmonic series as the interval between the first and second harmonics.

A (440 Hz) and A (880 Hz) are completely different sounds to me. Does this mean I'm tone deaf?

A recent episode of the podcast Surprisingly Awesome about music theory featured the line: So just to be clear, pretty much every human, when they hear a 440 or an 880, it’s going to sound like the same note. But they don't sound the same to me.…

Why do octaves sound equivalent?

It is, I think, a perfectly clear observation that one note an octave above another note sounds as if it were the same in a certain sense; while they are by no means the same exact note, they are named with the same letter, and one can for example…

Why does the octave number change between B and C?

I noticed that everywhere I read about music in scientific pitch notation, I see the notes in ascending pitch as in: A2 B2 C3 D3 E3 F3 G3 A3 B3 C4 Instead of what I expected, which was A2 B2 C2 D2 E2 F2 G2 A3 B3 C3 So why does the octave number…

Speed of playing notes in different octaves

Is it common for pieces to have lower notes played slower? Do instruments with lower registers typically play slower? I ask because notes in lower octaves are closer together in frequency. For example, A0 to A#0 is about 1.6 Hz different while A1 to…

Musical systems with more than 12 notes

From what I remember of music theory, all music (at least Western music) boils down to scales that revolve around the 12 notes (circle of fourths/fifths). I know there are scales in different regions that have different combinations of those notes…

Why don't two Boomwhackers with a one-octave pitch difference have a 2:1 length ratio?

I frequently use the tuned percussion tubes Boomwhackers in my elementary music teaching. I noticed something odd about them. When I compare the smaller and larger C tubes, they sound one octave apart. The sound decays too quickly for me to verify…

Does octave not matter when tuning?

Why does it not matter what octave you're tuning to? If you wind a string to two different octaves of the same note, surely it's going to have a big effect on the sound, no?

Is doubling the root when converting guitar chords to piano wrong?

If you take guitar chords and put them into sheet music for piano, should you double the root (CEGC) or not (CEG)? And if you do is it wrong because you'd have parallel octaves? I mean I know parallel octaves are wrong to use in music theory…

Was the term "octave" coined after the development of early music theory?

I have some confusion as to the use and history of the word octave in the context of music and tuning systems. The (western) tuning system comes from the Pythagorean division of the octave, based on consonant frequencies, found by simple ratios.…

8 below note played as octave or singular note?

I'm working on the piano solo version of Rhapsody in Blue, and I'm unsure - when there is an 8 underneath this E, is it meant to be played as just the lower E, or as a full octave (as in the measure before)?
