Air & Physical Foundations
Posture, breathing, hold, and assembly — everything before the first buzz
Assembly & Instrument Care
Assembling the Trumpet
- Open the case on a flat, stable surface — never on the edge of a chair or stand.
- Remove the trumpet by the bell or bell brace — never by the valve section.
- Insert the mouthpiece with a gentle twist (about a quarter turn) to seat it — never slam or force it in.
- If a mouthpiece gets stuck, use a mouthpiece puller only — never pliers or force.
- Before playing: pull the tuning slide out about ½ inch as a starting point.
- Check that all valve slides move freely before playing.
Daily Care
- Oil valves before each playing session — 2–3 drops of valve oil per valve.
- Empty water key(s) frequently during playing.
- Wipe down the instrument after playing to remove moisture and fingerprints.
- Store with mouthpiece removed.
- Weekly: grease tuning slide and all valve slides with slide grease.
- Monthly: run a snake brush through the leadpipe.
- Yearly: professional ultrasonic or chemical cleaning recommended.
Warning
Never force a stuck mouthpiece. A mouthpiece puller costs $10 — pliers cost hundreds in dent repair. Every band room should have a mouthpiece puller.
Posture & Holding Position
Seated and Standing Position
- Sit on the front half of the chair, feet flat on the floor, back straight, shoulders relaxed and down.
- Standing: feet shoulder-width apart, weight evenly distributed.
- The trumpet is held with the bell angled slightly downward — about 10–15 degrees from horizontal.
- Head level — do not tilt up to reach the mouthpiece.
- Bring the instrument to your face, not your face to the instrument.
Hand Position
- Left hand is the support hand — wraps around the valve casing with the ring finger in the third valve slide ring (for intonation adjustments).
- Left thumb wraps around the first valve slide saddle or casing.
- The left hand holds all the weight of the instrument.
- Right hand operates the valves — fingers curved naturally over the valve caps, pressing with fingertip pads.
- Right hand should be completely relaxed, carrying no weight.
- Right pinky rests on top of the pinky hook, not curled inside it.
Key Idea
The right pinky hook is for balance, not support. Students who curl their pinky inside the hook and press up are using mouthpiece pressure instead of air to play high notes. This is the #1 bad habit in young trumpet players.
Breathing for Brass
Teaching Tip
For generalizable breathing pedagogy applicable to all instruments, see the Hub: Breathing Principles. Below is what's specific to trumpet and brass.
Natural Breathing
- Breathing for brass playing is an extension of natural breathing — not a special technique.
- Dixon: "Calm mind, calm body."
- Don't consciously push the belly out or lift the chest — air creates any necessary expansion.
- Think of breathing in as relaxing and opening, breathing out as a steady, warm stream.
- Trumpet requires the fastest, most focused air of any brass instrument due to the small bore.
The Concert B♭ Exercise
- Have students breathe in for 4 counts, then sustain a concert B♭ (open on trumpet = written C) for as long as possible with a steady, even tone.
- This develops air capacity and air control from Day 1.
- The trumpet's small bore means air efficiency matters — a full breath should sustain a note for 15–20 seconds in beginners, building to 30+ seconds.
- Use this as a daily warm-up from Day 1.
Common Breathing Mistakes
- Raised shoulders on inhale (tension).
- Shallow chest breathing — only using the upper lungs.
- Gasping / noisy inhale.
- Puffed cheeks — air escaping laterally instead of channeling forward.
- Holding breath before playing (creates tension at the start of the note).
- "Huffing" — using short, choppy breaths instead of one full, relaxed inhalation.
