What's the opposite of "out loud"? I mean, "out loud" as in "singing out loud", what's the opposite of that? Like instead of singing for real, you do it in your head? What's the best way to say it? I am trying to find a better way to say "Sing inside your head".
If your lips move while you're reading a book, this is sometimes described as reading silently. The same expression could be used for singing:
Singing out loud.
→ Singing silently.
This wouldn't necessarily mean your lips are moving (although I've seen this happen, along with arm gestures to keep time to the imagined music), but that you are mentally listening to the words and notes even though you aren't physically vocalizing them.
You can use any of the following as they are antonyms of out loud: inaudibly, silently, soundlessly, voicelessly.
- "She was singing inaudibly."
"I am singing silently."
"The mimes were singing soundlessly."
"Tom had a sore throat and was forced to stand in the choir singing voicelessly."
And these are near antonyms of out loud: faintly, feebly, low, noiselessly, quietly, softly. They aren't truly opposite of out loud.
Hope this helps
