Lime Tree Arbour
(A song that protect us)
14 Now the Spirit of the Lord had departed from Saul, and an evil [a] spirit from the Lord tormented him. 15 Saul’s attendants said to him, “See, an evil spirit from God is tormenting you. 16 Let our lord command his servants here to search for someone who can play the lyre. He will play when the evil spirit from God comes on you, and you will feel better.” 17 So Saul said to his attendants, “Find someone who plays well and bring him to me.”
1 Samuel 16:14-17
Hell is located at the 64th of the Putvinskio Street in Kaunas, Lituania; a three-story building - unlike the one of 9 floors that Dante talked about - in where 3000 demons of different times, places and religions cohabit, going from the sympathetic and nice devil of Western Europe to the scary AfroAntillan devils. This place is known as the Žmuidzinavičius Museum or The Devil’s Museum.
The museum’s collection was originally created by painter Antanas Žmuidzinavičius, and by the time of his death, in 1996, it just had 260 sculptures; since then all the people that want to free themselves of their own demons can send them as a donation to the museum, meaning that nowadays the collection has more than 3000 pieces.
The most common way that the devil is represented is the goat: “the big bastard”, who, according to the demonology, is called Baphomet, leader of the other demons and main character within Satan’s church.
According to a research published by the Department of Comparative Hearing of the University of Toledo in Ohio[i], USA, goats - and therefore Satan - have a range of audible hearing that goes from 78 to 37000 Hz, this sensibility in the hearing of high frequencies helps the ungulates to establish a difference between a sound that comes from the front and from behind (binaurality’s only gotten with low frequencies). Even if it’s impossible to be completely certain, if we compare the goats’ isophonic curve with human being’s, we can speculate that their auditory threshold of pain starts at 100 and 104 dB[ii].
Keeping this in mind, three ultrasonic speakers[iii] play the melody of Lime Tree Arbour that’s been elevated six octaves[iv] at a power of 120 dB, producing that in a 6.31 mts radio in which the speakers constitute its center, a space is created and in it the sound intensity produces a discomfort to the devil that forces him to step back, Vade retro satana and with this a pergola is created, a shelter in which music can keep us from the devil, an opposite and complementary space of the 64th of the Putvinskio Street.

[ii] A goat would suffer the same damage with 100-104 dB than a human with 120dB.
[iii] In order to create the whole circumference there are needed 3 speakers because of the fact that the angle of dispersion of each is 120 degrees.
[iv] To achieve that the melody could only be heard by goats (and some other mammals), it is necessary that it sounds at a frequency that oscillates between 25 and37 kHz approximately; this range is between sol10 (25038.592 Hz) and re11 (37589.12 Hz), that’s why the music had to be adapted: by compressing the two octaves that the original song was composed with (do2 - sol4) to 4 notes (sol3 - re4), creating a microtonal melody and then raising it to 6 octaves.
