The problem:
* Missing subject: The second part of the sentence ("and she decided to audition for in spring") lacks a clear subject for the verb "decided".
* Unclear object: The phrase "for in spring" is unclear. It's not grammatically correct to use "for" in this way.
Here's how to revise the sentence:
1. Separate sentences: The easiest solution is to break it into two sentences.
* Sarah loved the sound of the choir at the recital.
* She decided to audition for the choir in the spring.
2. Combine with a conjunction: You could combine the sentences using a conjunction like "and" or "so".
* Sarah loved the sound of the choir at the recital, and she decided to audition for the choir in the spring.
Diagramming the revised sentence:
Let's diagram the revised version (sentence 2 above):
```

Explanation:
* Main subject and verb: "Sarah" and "loved" are the main subject and verb of the sentence.
* Direct object: "sound" is the direct object of the verb "loved."
* Modifiers: "the," "of the choir," "at the recital" are modifiers that describe the noun "sound."
* Conjunction: "and" connects the two clauses.
* Second subject and verb: "She" and "decided" are the subject and verb of the second clause.
* Infinitive phrase: "to audition" is an infinitive phrase acting as the direct object of "decided."
* Prepositional phrase: "for the choir in the spring" is a prepositional phrase modifying "to audition."
