Tonight's musical interlude - the beautiful and ancient (circa 9th Century) hymn Veni, Creator Spiritus, in celebration of Pentecost Sunday, performed by the Schola Gregoriana Mediolanensis in Milan, Italy:
The lyrics in the sung Latin, with a loose English translation below each verse:
Veni, creator Spiritus
mentes tuorum visita,
imple superna gratia,
quae tu creasti pectora.
Come, Holy Ghost, Creator blest,
and in our hearts take up Thy rest;
come with Thy grace and heav'nly aid,
To fill the hearts which Thou hast made.
Qui diceris Paraclitus,
altissimi donum Dei,
fons vivus, ignis, caritas
et spiritalis unctio.
O Comforter, to Thee we cry,
Thou heav'nly gift of God most high,
Thou Fount of life, and Fire of love,
and sweet anointing from above.
Tu septiformis munere,
digitus paternae dexterae
tu rite promissum Patris
sermone ditans guttura.
O Finger of the hand divine,
the sevenfold gifts of grace are thine;
true promise of the Father thou,
who dost the tongue with power endow.
... And the gates of hell shall not prevail against it. [Matt. 16:18]. In celebration of Pentecost Sunday, generally considered the birthday of the Church. May the Holy Spirit enkindle the fire of Divine Charity in our hearts.
Tonight's shocking musical interlude, courtesy two electrical engineering students - House of the Rising Sun, played on seven foot tall Tesla coils:
From the video's description:
... These are two gigantic solid state musical Tesla Coils. A Tesla Coil is a special type of transformer invented by Nikola Tesla that is able to generating extremely large voltages using a phenomenon known as electrical resonance. Each coil in this video is capable of generating a 13 foot spark. This equates to about 500,000 volts of electricity.
The primary drive system for the coils consists of high power semiconductors arranged into an H-Bridge switching configuration. During a spark event, the coil is pulsed on for a few hundred millionths of a second. During this short time, thousands of amps circulate within the primary tank circuit and the energy is coupled into the secondary resonator through magnetism.
So what appears to be a continuous burst of sparks is actually a specific number of sparks generated per second. By modulating the number of sparks that emit from the coil each second, different tones can be produced by the coils. ...
Salve, Regina, Mater misericordiae,
vita, dulcedo, et spes nostra, salve.
ad te clamamus exsules filii Hevae,
ad te suspiramus, gementes et flentes
in hac lacrimarum valle.
Eia, ergo, advocata nostra, illos tuos
misericordes oculos ad nos converte;
et Iesum, benedictum fructum ventris tui,
nobis post hoc exsilium ostende.
O clemens, O pia, O dulcis Virgo Maria.
And the common English translation:
Hail, holy Queen, Mother of Mercy,
our life, our sweetness and our hope.
To thee do we cry, poor banished children of Eve;
to thee do we send up our sighs,
mourning and weeping in this valley of tears.
Turn then, most gracious advocate,
thine eyes of mercy toward us;
and after this our exile,
show unto us the blessed fruit of thy womb, Jesus.
O clement, O loving, O sweet Virgin Mary.
