The essay brims with passion and communicates a clear sense of what inspires the writer, i.e., music. It paints a vivid picture of how playing music exhilarates the writer and the role it plays in their lives. However, parts of the essay can still be improved to emphasize the candidate's qualities and the effects of their inspiration.

1. Informality: The essay is written in a somewhat casual and informal tone. While this makes the essay sound conversational and genuine, an overly casual tone might not be optimal for a college application. For example, phrases like "Hope that helps and brings a smile to your face." may seem too relaxed. Instead, strive for a balance where your unique voice and personality can still shine through, but where your words reflect mature contemplation and seriousness of purpose.

2. Lack of Personal Experiences: The essay mentions the enjoyment derived from playing the piano but lacks specific anecdotes or detailed experiences that would elevate the narrative. Details such as moments when you mastered a difficult piece, or when your music particularly resonated with a listener would make the passion tangible.

3. Non-Expanded Inspiration: While the essay tells us that the writer finds inspiration in music and revered pianists, it would be beneficial to explain how this inspiration influences other aspects of your life. For instance, does music inspire you to study certain subjects, engage in community service, or view the world in a particular way? This would provide a more well-rounded understanding of your inspiration.

4. Connection to Yale: Since this is for a Yale application, consider mentioning how this passion can be further explored at Yale. Maybe there's a specific course or extracurricular activity you’re excited about. This could help display your interest in the university and how smoothly you'd assimilate academically and socially.

5. Ending: The essay concludes on a slightly abrupt note. A concluding paragraph that encapsulates your source of inspiration and briefly hints at your future aspirations or goals, tying your passion for music back to your vision for your time at Yale or your career, would round off the essay well. This ties your inspiration to your future, presenting a holistic view of why your inspiration is crucial to you.

The essay is a good start. It provides a fair representation of your personality, showing a balance between academic and extracurricular interests, as well as a sense of humor. However, several aspects can be improved for more depth and specificity.

1. Show, Don't Tell: You've mentioned your interests, but it's better to offer relevant experiences that visually depict these activities. For example, instead of simply stating your interest in books and soccer, you could relate an incident where knowledge from a novel strategically played a role in a soccer match.

2. Harvard Reference: The mention about choosing Harvard appears generic lacking depth; it can be applied to any highly reputable university. Instead, illustrate distinct aspects of Harvard that specifically align with your interests or goals. For example, maybe there's a professor within your chosen major with whom you would love to work.

3. Anecdotes or Stories: Adding anecdotes or stories about your community work or your struggle with a bag of gummy bears will not only make the essay more engaging, but it will reveal more about your personality and character.

4. Clearer Transitions: The transitions between different parts of the essay can be smoother and more natural. For instance, you abruptly switch from talking about soccer to Harvard which may confuse readers momentarily. A transitional sentence could mitigate this issue.

5. Values and Character Traits: Try to provide implicit insights into your values or character traits through your experiences and interests. For instance, volunteering indicates a sense of responsibility and commitment to the welfare of others. Your fascination for books could demonstrate intellectual curiosity and open-mindedness.

6. Conclusion: The ending could be more impactful or persuasive. Instead of just hoping for great times at Harvard, you could express enthusiasm about contributing positively to Harvard and its community with your future roommate. Remember, the purpose of this essay is to demonstrate what you would contribute to the Harvard community and how you would engage with your future roommate. Tailoring anecdotes to reveal more about your character and aspirations will allow the essay to resonate better with the committee.
