The sound of an organ pipe is made up of a set of harmonics formed by acoustic resonance, with wavelengths that are fractions of the length of the pipe.There are nodes of stationary air, and antinodes of moving air, two of which will be the two ends of an open-ended organ-pipe (the mouth, and the open end at the top).

A flue stop usually at 4 ft or 2 ft pitch but sometimes 8 ft pitch; similar tone as Spitz Flute. Gravissima (Latin) Gravitone (Latin) Acoustic Bass (English) Basse acoustique (French) Flute: A name for a resultant 64 ft flute (a 32 ft stop combined with a 21 + 2 ⁄ 3 ft stop, which is a fifth, producing a difference tone of 8 Hz on low C).
The harmonic series (also overtone series) is the sequence of harmonics, musical tones, or pure tones whose frequency is an integer multiple of a fundamental frequency. Pitched musical instruments are often based on an acoustic resonator such as a string or a column of air, which oscillates at numerous modes simultaneously.
The term "acoustic resonance" is sometimes used to narrow mechanical resonance to the frequency range of human hearing, but since acoustics is defined in general terms concerning vibrational waves in matter, [1] acoustic resonance can occur at frequencies outside the range of human hearing.
An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. [1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz.
The resonant frequency of a vessel flute is given by this formula: (heavily simplified, see simplifications) [8] p i t c h o f t h e n o t e = ( a c o n s t a n t ) × t o t a l s u r f a c e a r e a o f o p e n h o l e s t o t a l v o l u m e e n c l o s e d b y t h e i n s t r u m e n t {\displaystyle pitch\ of\ the\ note=(a\ constant)\times ...

The bass flute is an octave lower than the concert flute, and the contrabass flute is an octave lower than the bass flute. Less commonly seen flutes include the treble flute in G, pitched one octave higher than the alto flute; soprano flute, between the treble and concert; and tenor flute or flûte d'amour in B ♭ , A or A ♭ [ citation ...
