What mnemonic device is commonly used for musical notes in the bass clef?

The mnemonic device "All Cows Eat Grass" is specifically used for the notes in the spaces of the bass clef. In this clef, the spaces from bottom to top correspond to the notes A, C, E, and G. This phrase helps musicians easily recall these notes by associating them with a simple and memorable sentence.

In contrast, other mnemonics mentioned focus on different aspects of musical notation. For example, "Every Good Boy Deserves Fudge" is used for the lines in the treble clef, rather than the bass clef, while "FACE in the Space" pertains to the spaces in the treble clef. "Good Boys Deserve Food" serves a similar purpose as the first but is also aimed at the treble clef's lines. Therefore, "All Cows Eat Grass" aptly represents the bass clef spaces and is the appropriate answer for this question.
