ADJUSTING SCREW –  a small screw that causes two keys to move together in combination to create a specific note.

CLEAN, OIL, ADJUST – Also referred to as a C.O.A, it’s the annual maintenance performed on the instrument. Includes cleaning, oiling, hand polishing on the instrument and mechanism to remove tarnish, head joint cork replacement, adjustments, removal of lost motions, leak detection and pad replacement as necessary.

LEAK – happens between the tone hole and the pad where air is escaping creating a slight change in the tamber or/color of the note. It can make the entire instrument not playable, depending on how big and how many leaks  you have.

LOST MOTION – happens when you press a key and it doesn’t engage the next adjusted key right way and it feels like a bump when you depress the key.

OVERHAUL – all pins are pulled, flute is hand cleaned to remove tarnish, new oil is put in, corks, felts, u0026amp; pads are replaced. Pads are shimmed to remove leaks u0026amp; flute is adjusted to play. Dents are removed by quote.

SHIM –  a small washer made from plastic or paper that it’s put between the pad and the key to help seal them to the tone hole.

CLICKS- usually metal to metal and you’re missing a cork, VERY noisy when playing the flute.
