Trumpet Owners Manual

Review us on

Cecilio trumpets are precision made instruments and are tested at our factory. Prior to shipping each instrument is inspected by skilled technicians at our Los Angeles distribution center. However, because trumpets are fragile instruments they can get out of adjustment in the shipping process. If this occurs you may need to get your new instrument adjusted by a local technician.

Getting Started

You must assemble, clean, and tune your new Trumpet prior to playing. Trumpets are delicate instruments and can be damaged easily. Handle with care. If you have a trumpet instructor we recommend you see him or her to assist you with assembling, cleaning and tuning your instrument for the first time.

If cannot wait, follow the steps below:


  • Hold the trumpet vertically with the bell towards the ground. Gently drop the mouthpiece into mouthpiece receiver letting the weight of the mouthpiece form the connection. To get an airtight seal twist the mouthpiece clockwise 1/4 turn


Never force the mouthpiece in place. Avoid knocking or striking the mouthpiece inward. This can cause the mouthpiece to become permanently stuck. If your mouthpiece becomes stuck please visit your local repair shop. They have special tools to remove mouthpieces. Never use pliers or other gripping tools to remove a stuck mouthpiece.

Tuning your Trumpet

  • Pitch is affected by temperature, so be sure to warm up your instrument before playing by blowing air through it.
  • Four tuning slides are incorporated in to your Cecilio Trumpet. These enable the fine-tuning and intonation of the instrument to be adjusted.
  • Make sure that all the trumpet tuning slides are pushed all the way in.
  • You can use a chromatic tuner or piano
  • The tuning pitch for the Bb trumpet is C, played using an open valve combination in the 3rd partial.
  • Adjust intonation with the main tuning slide by pushing in or pulling out in small increments.
  • Not every pitch on the trumpet will be in tune as fine tuning of the intonation is done with the embouchure and valve slides.

For more guidance on tuning your instrument we recommend that you seek advice from a retail store, music teacher, or technician.

Playing your trumpet

While playing, saliva accumulates within the instrument. To prolong the life and playing condition of your instrument this fluid must be expelled on a regular basis with the spit valve. The spit-valves are located on the main tuning slide and the 3rd valve tuning slides.

  • Hold the trumpet at a 45 degree angle towards the ground
  • Holding one spit-valve open at a time, blow through the instrument to expel excess water.


For your convenience a cleaning cloth and valve oil are included your Cecilio Trumpet. We recommend that you use these products and the products contained in the Cecilio Trumpet Care Kit (Model C-TCK) to maintain the condition of your trumpet. (see below for maintenance suggestions)

It is important to disassemble and thoroughly clean the instrument after playing, and especially prior to placing it in its case for storage between playing sessions. We recommend that you follow the routine below to ensure that the instrument is kept in peak condition by using the products contained in the Cecilio Trumpet Care Kit (Model C-TCK).

In addition to the steps described below we recommend that you take you instrument to a skilled technician at least once a year to be serviced.

Remember the better you care for your instrument the more enjoyment and please you will receive 
from it.

Cleaning valves

Regular oiling of the valve pistons is fundamental to the smooth operation and playing of the instrument.

Valve oil (provided) should be applied (sparingly) to each valve. To apply valve oil, follow the procedure for cleaning and maintenance of the valve piston as described below:

  • Unscrew valve cap to remove valve piston
  • Remove valve piston in a straight line. Do not twist piston.
  • Valve pistons and casings are NOT interchangeable. Each valve pistons and casting have a number on them (# 1, 2, and 3), make sure you place the valves in the correct castings.
  • Inspect the valve piston and casing. If there is any damage to the valves or valve casings, take your instrument to your dealer or local technician for repair.
  • Apply valve oil (enclosed) sparingly to ensure adequate lubrication
  • Place the valve carefully back into the proper casing, aligning the valve guide with the guide slot. Tighten the top valve cap. Move piston up and down to ensure even oil coating over the entire surface.

Valve Casing

  • The valve casings should be cleaned on a weekly basis.
  • To clean valve casing remove piston as described above
  • Insert a valve brush through the valve casing and pull back up. Repeat several times. You can also use the brush to clean the portholes of the valve pistons.
  • Replace pistons as described above.

Tuning Slides and lead pipe

  • Carefully remove all tuning slides and clean with a snake-brush by running it through the insides 
    of the slides
  • Clean the lead pipe while the main tuning slide is removed by dropping a snake (contained in Cecilio Trumpet Care Kit Model C-TCK) into the lead pipe and push through to mouth piece receptacle. Remove and repeat several times.
  • Use a small amount of slide-grease to lubricate the slides before replacing them in the 
    correct receptacles.


  • Gently remove any dirt, perspiration and finger marks from the surface of the instrument with the cleaning/polishing cloth (provided).
  • Rub briskly to return finish to its fine luster.

Cleaning the Mouthpiece

  • Soak the mouthpiece in a solution of warm soapy water. Using a brass mouthpiece brush scrub the inside and outside
  • Rinse thoroughly with clean, warm water.

Cleaning the Water Keys

  • A tone hole cleaner may be used to clean and dry the water keys.

Other helpful hints

  • Avoid fluids that contain sugar prior to playing. If drinking or eating prior to playing rinse out 
    your mouth.
  • Remove your trumpet from its case by lifting it from the lead pipe and bell
  • Always remove the mouthpiece from your trumpet when not in use
  • Always store your trumpet in its case when not in use to prevent damage
  • Your instrument is a valuable item and should be treated with respect. By following the guidelines above your instrument should provide you and your listeners with hours of pleasure
  • If you remain uncertain after reading these guidelines on how to assemble and clean you’re Cecilio Trumpet, seek advice at your local music store or from a music teacher.
  • Damage caused by incorrect assembly and/or inappropriate handling will not be covered 
    by the warranty.
