The present invention relates to a set of organ pipes including at least 54 pipes, characterized in that said set has a variation in the richness of the harmonics generated by said pipes during use, and in 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, preferably between 200 and 300 Hz, wherein said maximum is different by at least 20dB with respect to the ratio of the intensity of the first harmonic to the fundamental of the pipe producing the lowest frequency note. |
