I hear you. A half‑off riff can feel like a detour, but it’s also a reminder that music is a living thing. In a disciplined routine, a little spontaneity keeps the voice from becoming rigid. I suggest setting a small, scheduled slot for free jamming—just enough to let the ear explore, then return to the structured practice. That way the improvisation informs, rather than distracts, the pursuit of perfection.

That’s the spirit—just make sure the rebellion stays a brief, intentional pause, not a distraction. Your ears will thank you for the freedom, and your practice will still feel tight and focused. Good luck, and enjoy the little detour.
