On March 27th 2005, 'Arpeggi' was premiered at the Ether Festival. Thom sang while Jonny played Ondes Martenot. They performed the song with the London Sinfonietta (including six Ondes Martenots played by Valerie Hartmann-Claverie, Bruno Perrault, Nathalie Forget, Fabienne Martin-Besnard, Nadia Ratsimandresy and Pascale Rousse-Lacordaire) conducted by Martyn Brabbins with the Arab Orchestra of Nazareth.

This video, edited from two sources for this website, uses the audio recording that was aired by the BBC:

in the deepest ocean
the bottom of the sea
your eyes
they turn me

why should i stay here
why should i stay

i'd be crazy not to follow
follow where you lead
your eyes
they turn me

sunk without a trace
the bottom of the deep
your eyes, they turn me

turn me into phantoms
i follow to the edge of the earth
and fall off

everybody leaves
if they get the chance
and this is my chance

i get eaten by the worms
and weird fishees
picked over by the worms
and weird fishees

hit the bottom to escape
'Arpeggi' was one of the titles that appeared on the blackboard the band used during two weeks of rehearsals from september 19th to 30th 2005. At the end of that session, Colin posted a picture of this board on Dead Air Space on september 30th, unfortunately (and probably intentionally) in rather low resolution, so that some of it can't be deciphered:
The following pictures show the band recording 'Arpeggi' during the sessions with Mark "Spike" Stent.

On January 10th 2006, the first of those pictures was posted on Dead Air Space under the title 'winter studio', the other two were posted on February 22nd 2006 (click images to enlarge):

On March 8th 2006, shortly after sessions with Mark Stent had come to an unfruitful end, another photo of a blackboard (and a perhaps slightly worried Ed) was posted on Dead Air Space. A tour had been scheduled for may and june to escape the frustration of the recent sessions and to breathe new life into the project. Rehearsals for the upcoming dates had begun recently, and this board shows which new songs were at this point considered for inclusion in the setlists. 'Arpeggi' was one of these, and would indeed be played (click image for full size):
On May 1st 2006, Thom and Jonny performed 'Arpeggi' acoustically for the first time at a Friends Of The Earth benefit gig at the Koko in London:
In December 2006, this photo was taken at Nigel's studio at The Hospital in London. It was posted on Dead Air Space on February 6th 2007 and was titled "Ed and Thom in Arpeggi":

On March 29th 2006, a short videoclip appeared in the Hodiau Direkton section. The clip featured Thom singing a line from the end of the song:
On June 15th 2007, Nigel posted a video on Dead Air Space, that showed the playback of a reel of assembled tape snippets, which were cut out during the editing process.

The reel contains 2 fragments from the finished recording of 'Weird Fishes/Arpeggi', which actually flow seemlessly into each other and can be combined if one switches the order around:

On November 9th 2007, an electronic piece that uses the backing vocals from 'Weird Fishes/Arpeggi' was heard in the webcast:

An excerpt from a remix of 'Weird Fishes/Arpeggi' was used at the end of Scotch_mist, which was produced in mid december 2007. The full version was posted in early may 2008 on Thom's page at w.a.s.t.e. central. The file name suggests it was created by Jonny:
