"You stayed in key 87% of the time. The data shows your strongest moments and the areas that will have the biggest impact."
Cover Song Sprint
Close the gap on your cover song in 14 days
For the audition, the performance, or the live set where your vocals have to land.
Choose one song and upload your starting take. You'll get a visual Performance Map, one priority to practice, and personal notes from Eric on every coaching session. Re-record over 14 days until the improvement is something you can hear.
During this initial five-singer Sprint, I personally review every coaching session to make sure the guidance is accurate, specific to your performance, and focused on changes you can actually make.
A clear phone video is all you need - no fancy gear.
For single-performer vocals. Accompaniment optional.
Musicians who stopped guessing.
"Seeing my actual pitch accuracy score gave me the objective feedback I needed. No more guessing if I hit the notes."
"I always thought I was on pitch. Seeing 71% in key was the wake-up call, and the weekly focus tells me exactly what to fix. Watching that number climb is addictive."
"It is the first tool that told me what to practice instead of just that I sounded good. The #1 focus each week is gold, and the drone and metronome are right there to work on it."
"Cheaper than one lesson a month and I run five takes a week. My covers have never sounded tighter."

How you actually improve
It's a system, not scattered feedback
Anyone can tell you a take sounded good or shaky. Improving quickly takes a loop you can repeat. Here's ours:
01
Perform
Record your take of the song you're chasing, and upload it.
02
Listen
Get your Performance Map and full coaching session, with Eric's note added on top.
03
Understand
See your one focus: not ten problems, the single thing to fix first.
04
Implement
Practice that one change, re-record, and perform it again.
That's the whole method: one focus at a time, run over and over, for 14 days.
See your voice, note by note
Your Performance Map
Every upload comes back as a Performance Map: your recording and waveform, measured dynamics, and note-and-tuning evidence when the vocal signal supports it. You can connect the coaching to exact moments instead of guessing what changed.

What every upload gives you
Specific, timestamped, one focus at a time
Your instant coaching session

Plus Eric's personal note on top

"The session nailed the read - my two cents: your verse is already intimate, so let the chorus get almost uncomfortably big. That contrast is your money moment in this song."
How the Sprint works
DAY 1
Choose one song and upload your baseline
Paste the YouTube version you want to sound like, tell us what "ready" means for you, and upload a clear phone video of where the song is today. That is your baseline.
You get: your first Performance Map and coaching session, plus Eric's personal comments on your baseline.
DAY 2
Get your one prioritized focus
Not a list of ten problems. The one thing to work on first, with a specific practice assignment to go with it.
You get: your #1 focus and exactly how to practice it.
DAYS 3-12
Submit retakes
Practice the focus, record, upload. Every retake gets a fresh Performance Map and full session as soon as analysis finishes. Eric adds his personal notes on top.
You get: Eric's comments and suggestions on every single retake.
DAY 14
Get your founder-reviewed final verdict
Day 14: hear your first take and your final take side by side.
Your baseline and your final take, side by side: what has changed, what is still inconsistent, and what to work on next.
You get: your first take and your last, side by side in your own ears, plus Eric's note on what to work on next.

My eyes and ears on every take
A focused loop, plus my personal review
Eric Neff · Founder of Performance Coach · Musician for 20+ years
Software can identify patterns, but useful coaching requires judgment. During this founding Sprint, I personally review every coaching session to make sure the guidance is accurate, specific to your performance, and focused on the change that will help you most.
You won't be left interpreting an automated score by yourself. If the system misses something, I correct it and add my personal notes.
