thank you

You're welcome.

Actually, the phrase you mentioned, "a musical group for four instruments," does not appear to be an absolute phrase. Rather, it is a prepositional phrase that functions as an adjective.

An absolute phrase is a group of words that modifies an entire independent clause in a sentence, usually consisting of a noun or pronoun followed by a participle (ending in -ing or -ed) and any additional modifiers or objects. Absolute phrases often provide additional information about the subject or the action of the sentence. They are usually separated from the rest of the sentence by a comma.

For example, an absolute phrase could be: "His hands trembling with excitement, he opened the gift."

In your sentence, "he learned to play in a quart a musical group for four instruments," the phrase "a musical group for four instruments" is a prepositional phrase acting as an adjective. It describes the noun "quart," giving more information about the kind of musical group. Prepositional phrases typically consist of a preposition (e.g., "in," "on," "at") followed by a noun or noun phrase (in this case, "a musical group for four instruments").

Now, if you are looking to rephrase the sentence using an absolute phrase, you could say: "Learning to play, he joined a quart, a musical group for four instruments." In this revised sentence, the absolute phrase "Learning to play" modifies the subject "he" and adds additional information about the action of learning.
