Among the ceremonies of the cathedral of Seville is one sufficiently unique to be deserving of notice. _El baile de los seis_ (dance of the six), is performed by eight youths--probably by six originally--every evening during the feast of the Conception. It takes place in front of the high-altar, on which her statue is placed on that occasion. The service is one of especial solemnity; and, as such, accompanied, unfortunately as on all such occasions, by an orchestra of violins, to the exclusion of the organs. The singing commences at four o'clock in the afternoon, in the choir, and continues until half-past six, when all move in procession through the great railing, across the transept, and ascend the flight of steps which lead to the Capilla Mayor. Here they take their seats according to rank, on benches placed in rows from east to west, fronting a space which is left open down the centre, in front of the altar. The orchestra occupies a corner near the railing; and on the two front benches are seated--four facing four--the eight youths, dressed in the ancient Spanish costume, all sky blue silk and white muslin, and holding each his hat, also light blue, with a flowing white feather. The chorus now recommences, but speedily drops; when the orchestra sounds a beautiful air in the waltz measure. This is played once by the instruments alone, and joined the second time by the voices of the eight boys, or youths of the age of sixteen to eighteen; who, after having accompanied a short time, start to their legs, and continue in the same strain. At the next reprise they all, as if by word of command, place their hats on their heads, and one or two minutes after, the chant still continuing, advance, and meet in the centre, then return each to his place; advance a second time, and turn round each other, using the waltz step. After singing and dancing for about a quarter of an hour, the voices are exchanged for the sounds of castagnettes, which they have held all this time in their hands, and the measure becomes more animated; and thus they terminate the performance. The same ceremony is repeated each night of the seven; only varying the air of the waltz, of which they have two. This ceremony, now belonging exclusively to the cathedral of Seville, was originally performed in some other cathedrals; but has been gradually laid aside in all the others, having been found to occasion irreverent behaviour among a portion of the spectators. It was originally introduced among the observances in honour of the anniversary of the Conception, as a natural manifestation of joy; and such a genuine Spanish bolero would have been: but the slow time of the music, and the measured movements, adopted for the purpose of suiting the performance to the solemnity of the place, have changed the nature of the dance, and deprived it of everything approaching to cheerfulness.
