Melody following https://gallica.bnf.fr/ark:/12148/btv1b84262784/f230.item.zoom (F-Pn NAL 1535) with rectifications to fit the neumes in H's second hand (listed source). Those rectifications were made following Sandhofe. Alleluia from Sandhofe. The following neume items are synthetic: 'alleluia','venturus sit', '...tui sancto'.

Added brackets in the correct places. This Alleluia should be revised, the descending fourth is weird.
