Slides, valves, crooks (though they are rarely used today), or keys are used to change vibratory length of tubing, thus changing the available harmonic series, while the player's embouchure, lip tension and air flow serve to select the specific harmonic produced from
Saxophone baritones have occasionally been made in the straight style. Most commonly, however, the alto and tenor saxophones incorporate a detachable, curved "neck" above the highest tone hole directing the mouthpiece to the player's mouth while the instrument is held in a playing stance.
