"As you know, there are certain languages that lend themselves very easily to vocal use"

This quote by Neville Marriner is describing the fact that some languages are simpler to sing than others. Specific languages, such as Italian, French, and German, have a natural circulation and structure that make them ideal for vocal usage. This is due to the fact that they have a strong focus on tune and rhythm, that makes them much easier to sing. In addition, these languages have a large range of vowels and consonants that can be used to develop interesting and distinct noises. This makes them more suitable for vocal use than other languages, such as English, which has a more minimal range of noises. By understanding the structure of these languages, singers can use them to develop stunning and expressive music.
