## Description

Import a track and get a first take on the chords. Slow it down without changing the pitch, and fix anything on the piano roll. One-time purchase.

"How do they play that part?" — this app answers it.

Every musician hits the same wall sooner or later: working a song out by ear.
A song with no sheet music. A phrase you love. That intro.
By Ear PRO takes that wall down with four tools.

1. A head start on the chords
Import a track and you get a first reading of the chord progression.
Your ears still decide — you just don't have to start from nothing.

2. Slow playback that keeps the pitch
Play a fast phrase slowly without it dropping in pitch.
Combine it with AB repeat and you can loop the hard part as long as you like.

3. Work it out while you watch the piano roll
The chords sit on a piano roll in front of you.
See it, hear it, and correct it until it matches what you heard.

4. Start from a blank roll and write it yourself
Enter notes at your own pace from nothing at all.
Insert chords as you go and build the structure while you work.
