Pick a maqam, hear the scale played back at your practice speed, then play along on your oud — the coach listens and gives you spoken feedback, quarter-tones included.
Rast, Bayati and Saba use widely taught 24-tone interval approximations. Houzam's intonation varies more between teachers and traditions, so its default is a reasonable starting point — adjust the cents above to match what your teacher actually plays. Note detection uses autocorrelation on your mic input and works best for single, clearly plucked notes rather than fast runs.
