'Distinct' in the Bible

Now you [collectively] are Christ’s body, and individually [you are] members of it [each with his own special purpose and function].

Yet even lifeless things, whether flute or harp, when producing a sound, if they do not produce distinct [musical] tones, how will anyone [listening] know what is piped or played?

Thus also ye with the tongue, unless ye give a distinct speech, how shall it be known what is spoken? for ye will be speaking to the air.
