Set of organ pipes

A method for determining a rank of organ pipes in harmonic progression comprising:

• obtaining an organ of the prior art comprising a plurality of ranks of pipes;
• for each rank, measuring the harmonic components of at least one pipe at a minimum of one frequency
• choosing the pipes making up the rank of organ pipes in harmonic progression as a function of the harmonic components measured so that the ratio of the intensity of the first harmonic to the intensity of the fundamental is at a maximum at a frequency between 150 and 500 Hz, said maximum being different by at least 20 dB relative to the intensity of the ratio of the first harmonic to the intensity of the fundamental of the pipe producing the note at the lowest frequency.

An assembly of organ pipes comprising at least two flue pipes each comprising a front surface, a rear surface, two side walls, and at least one partition separating the individual flue pipes, the front surface being pierced with mouths having an upper lip and a lower lip in the space defined between the partitions, and languids being arranged inside the flue pipes defining a flue between the lower lips of the mouths and the languids, cavities defined under the languids comprising means for individually supplying the cavities with wind, and cavities situated above the languids defining the resonator of each pipe.
