Playing Technique
- Separate bass and upper voices · difficulty 4/5Use the fretting-hand thumb for low notes only where comfortable, then let the fingers articulate the upper chord. Each voice should sound independent; squeezing the whole grip makes notes choke or pull sharp.
- Mute the strings between chord fragments · difficulty 4/5Release fretting pressure and use the picking hand to stop sympathetic ringing before the next embellishment. Edge-of-breakup gain makes clean gaps essential to the riff's conversational rhythm.
- Keep hammer-ons lighter than the main chord · difficulty 3/5Drop the finger from close to the fret so the ornament speaks without jumping forward. Hitting every embellishment at full volume destroys the layered chord-melody effect.
- Use dynamics instead of more gain · difficulty 3/5Play the opening with a relaxed attack, then increase pick or finger force as the band grows. The amp should add a little hair under pressure while preserving the voicing throughout.

Tone Story / Why This Tone Works
- Style and eraThe 1991 Blood Sugar Sex Magik era expanded the band's funk rock with more harmony, restraint, and open space.
- John Frusciante's signatureThumbed bass notes, ringing upper voices, Hendrix-derived embellishments, and vocal-aware dynamics turn chords into melody.
- Distorted means edge of breakupOnly a hint of grit should surround the Strat-style attack; heavy saturation would collapse the inner chord voices.
- Why the riff carriesThe same articulate sound feels intimate alone and remains present when the full band enters, adding vulnerability without a wall of gain.
