If I Knew — Karaoke: Lyrics & Chords to Sing & Play Along
23 people have learned this song
Free karaoke for "If I Knew" by Bruno Mars: lyrics on screen with the chords above each line and a bouncing ball that lands on every word in time. Sing along, or play along on guitar or piano from the chord chart. Change the key to fit your voice, slow the tempo down. Key of Ab, 87 BPM.
This arrangement is a wonderful workout for smooth chord transitions in A♭ major, and at 87 BPM you have just enough breathing room to nail each change — but not enough to fake your way through sloppy hand shifts.
Your left hand follows an octave bass pattern, so lock that in first: practice it alone until the jumps between A♭, E♭, and the chromatic moves toward F♯ and G♭ feel automatic.
The real challenge lives in your right hand navigating thirteen chords, especially the shifts between C minor and its C minor 7 voicing and the momentary detour into A♭ minor — those color changes demand precise finger placement without hesitation.
I'd suggest looping the trickiest four-bar sections at around 60 BPM, hands separate, then gradually bring them together before pushing toward full tempo.
Watch your pedal work carefully; in a ballad this exposed, holding the sustain pedal through chord changes will blur everything into mud, so practice clean pedal swaps on every chord root change.
Once this clicks, you'll have real confidence handling chromatic bass movement and extended chord shapes in any pop ballad you tackle next.
