Why Ukulele Intonation Matters

Nut and Saddle Placement

Unfortunately not every ukulele is mathematically built to ensure that the nut and saddle are the exact distant apart to ensure pitch consistency/correctness throughout the whole neck.

Fret placement

Furthermore, nor are frets always placed in accordance with the 'pythagorous ratio', required for ukuleles (and other fretted stringed instrument) to intonate correctly. This is why you must check a ukulele's intonation prior to purchasing a ukulele (if buying online ask if they can demonstrate the intonation over video call).
