To start learning Mirai - I Přes To Všechno chords, build your understanding on these basic chords - Eb, Fm, Eb, Db, Fm, Db, Eb, Ab and Db in sequence. I suggest starting at a calm pace of 72 BPM, and as you gain confidence, approach the song's BPM of 144. Configure the capo to your vocal range and chord preference, remembering the key of Ab Major.
