4i Services is permanently searching the best mouthpieces on the music instrument market. Therefore, we can offer to our clients mouthpieces of highest quality.

Innovation and quality are our guidelines!

Mouthpieces are the starting point for producing the sound with a musical instrument and are influencing the embouchure, the tone, the confidence, and the endurance of every wind musician.

For Brass Instruments the following characteristics determine the quality of the mouthpieces:

The primary characteristics are the cup diameter (i.e. the inner diameter of the cup), the depth of cup,  the rim width of the cup, the diameter/size of the bore, the length of the inner bore as well as the form and size of the back bore.

Secondary characteristics are the material used for the cup, respectivly the plating of the cup and the outside form of the mouthpiece sector following the inner bore (thin or massive).

For Woodwind Instruments the following characteristics are important:

Primary characteristics are here the size of the chamber, the length of the table and the width of the opening.

For long tables and/or small openings strong reeds are recommended, for short tables and/or wide openings weaker reeds are recommended. (Note aside: the lenght of the table and the width of the opening is a matter of tradition: there is a French tradition, a German tradition, and a Austrian tradition for clarinet mouthpieces.)

Secondary characteristics are the used materials for the mouthpieces: Rubber, Acrylic, bakalite or metal. Metal mouthpieces are offeredn and in use especially for saxophones, because they produce a more brilliant and a kind of metallic sound.
