Uachtar-chanus - Highest note
Here an initial noun may be omitted, for uachtar-chanas again looks like a relative verbal form, 'which sings highest' (uachtar means 'top, upper part'). On p.36 we have Uachdarchanus, 'Highest D in alt'.

Note that this is the highest string of the Downhill harp. Other instruments had different highest and lowest notes. For more on Chanus see Cronan ioctar-chanus.
