other pieces of Ecclesiastical Music exist, in both. For instance, the fine Plain Chaunt 'Missa in Festis Solemnibus'—better known, perhaps, in a less pure form, as the 'Missa de Angelis' is in the Authentic Ionian Mode, throughout: and a particularly captivating Hypo-ionian melody has been preserved to us, in the Paschal form of the Responsory 'In manus tuas, Domine,' as given in the Mechlin Vesperal.
A strong prejudice existed against the Ionian Mode, in mediæval times, when the softness of its intervals gave so great offence, that it was commonly called Modus lascivus. The early contrapuntists seem also to have regarded it with grave suspicion. It was only as Art advanced, that the inexhaustible extent of its capabilities became gradually apparent. When first employed in polyphonic music, the Authentic scale was usually transposed (for the greater convenience of ordinary combinations of voices) with the customary B♭ at the signature; in which condition it is often mistaken for the modern key of F. Palestrina delighted in using it, with this transposition, as the exponent of a certain tender grace, in the expression of which he has never been approached; as in the 'Missa Brevis,' the Missa 'Æterna Christi munera,' the delightful Motets, 'Sicut cervus desiderat,' and 'Pueri Hebræorum,' and innumerable other instances. Giovanni Croce has also employed it in the Motet 'Virtute magna'—known in England as 'Behold, I bring you glad tidings': while in our own School, we find instances of its use in the imperishable little Anthem, 'Lord, for Thy tender mercy's sake,' and Gibbons's fine Service in F.
The Hypo-ionian Mode is less frequently transposed, in writing, than the Authentic scale, though it is sometimes found desirable to depress it a whole tone, in performance. This is the Mode selected, by Palestrina, for the Missa Papæ Marcelli; and by Orlando di Lasso, for his Motet, Confirma hoc, Deus—both which compositions are erroneously described, in the latest German reprints, as in the Mixolydian Mode.The melody of the Old Hundredth Psalm, in its original form, is strictly Hypo-ionian; and is given in its true Mode, transposed, in the masterly setting, by John Dowland, printed in Ravenscroft's 'Book of Psalms' (Lond. 1621). [See Hymn; Old Hundredth Psalm.]

IRISH MUSIC. Although it is not long since the opinion was generally entertained that Ireland had been sunk in barbarism until the English invasion, historical and antiquarian researches have established the fact that the island was in early times the seat of Christianized learning and a remarkable artistic civilization. Her music, however, and in particular her ancient school of Harp-playing, have from early times been in high repute, having been lauded in the writings of Brompton, Giraldus Cambrensis, and John of Salisbury (12th cent.). The latter writes thus: 'The attention of this people to musical instruments I find worthy of commendation, in which their skill is beyond comparison superior to that of any nation I have seen.' Fuller's words are equally strong: 'Yea, we might well think that all the concert of Christendom in this war [the Crusade conducted by Godfrey of Boulogne] would have made no music, if the Irish Harp had been wanting.' Fordun (13th cent.), Clynn (14th cent.), Polidore Virgil and Major (i5th cent.), Vincenzo Galilei, Bacon, Spenser, Stanihurst, and Camden (16th cent.), speak with equal warmth. Written music being however comparatively modern, no remains are existing, like the beautiful Irish illuminated MSS. and examples of ornamental Celtic metal-work, which would substantiate the praises of the above writers.
Three Irish airs, extracted from Queen Elizabeth's Virginal Book, are given in vol. ii. p. 793 of Mr. Chappell's 'Popular Music of the Olden Time'—(1) 'The Ho-hoane' (Ochone), (2) an 'Irish Dumpe,' and (3) 'Callino Casturame.' They are all in 6-8 measure, and seem deficient in the characteristic features of Irish melody. To the latter air there is an allusion in Shakespeare, Henry V, act iv. sc. 4, where Pistol addresses a French soldier thus:—'Quality! Calen o custure me!'—an expression which has greatly puzzled the critics. It is evidently an attempt to spell as pronounced the Irish phrase 'Colleen, oge astore!'—young girl, my treasure!The earliest published collections of Irish music are by Burke Thumoth (1720); by Neill
- In the Ratisbon Vesperal, this melody is reduced, from the Fourteenth, to the Sixth Mode; and a similar reduction, from Mode XIII, to Mode V, is by no means uncommon, in Plain Chaunt Office-Books.
