vocalism

Speaking or singing.

The exciting vocalism of Leontyne Price

The vowel sounds used in a language.

The vowels, sequence of vowels, or the quality peculiar to the vowels of a given word or group of words.

All forms contain a base *θirr- or *θurr-. Types 1 and 2 [which contain *θirr] may have been influenced by θirri̯are 'to screech', suggesting that the forms with *θurr- preserve the original vocalism.
