When they come together to make music, the Welsh sing their traditional songs, not in unison, as is done elsewhere, but in parts, in many modes and modulations. When a choir gathers to sing, which happens often in this country, you will hear as many different parts and voices as there are performers.
In musico modulamine, non uniformiter, ut alibi, sed multipliciter, multisque modis et modulis, cantilenas emittunt. Adeo ut in turba canentium, sicut huic genti mos est, quot videas capita, tot audias carmina discriminaque vocum varia.
