5th partials sit -14¢ flat! Pull C4 in ~1.3cm; play sustained D4 in raised 4th position.
Play 3 minutes of loose-jaw Pedal B♭1 (58.27Hz) to restore capillary blood flow.
Anchor 4th line = Middle C4 (#3rd pos), or read as Bass Clef up a fifth.
+33% tubing widens spacing to 6 positions (down to C2); pull F-slide 3.8cm for Low B1.
Never mix lubes! Clean inner/outer tubes, apply 2 drops on stockings + distilled water mist.
Run the ≥3s Vacuum Pop Test and flashlight-inspect the leadpipe for pinkish Red Rot.
