Trumpets can be easily drawn by simplifying the shapes.
When drawing a trumpet, the instrument can be simplified. One of the most effective ways to simplify a trumpet is to break it into simple shapes. By using ovals and rectangles to lay in the basic shape of the trumpet, the details are far easier to fill in correctly. Another easy way to draw trumpets is to draw some of the lesser known, but far more simple trumpets.
The Body
An easy way to draw the B-flat trumpet is to draw the instrument in sections, using simple shapes. To begin the body, draw a simple rectangle oriented horizontally, then slightly round the right-hand side. Draw the tapered tube attached to the rectangle, then flare out the end of the horn. Inside the flare of the horn, draw two ovals.
Finishing Touches
Elongate the top left side of the rectangle to form the top of the mouthpiece. In the middle of the rectangle, draw the three keys. Beneath the peg of each key, lightly draw in a rectangle. Draw the swirl of the body over the key tubing, then go back and darken your lines.
Piccolo Trumpet
Another easy way to draw trumpets is to draw a less complicated trumpet. The piccolo trumpet -- which has a simpler body than the B-Flat trumpet --- can be drawn starting with four vertical rectangles, with keys on top. The horn can be drawn straight out from the keys, with the mouthpiece extending in the other direction. The body of the trumpet is a simple oval shape behind the keys and under the horn.
Baroque Trumpet
An even simpler trumpet is the Baroque trumpet. For this trumpet, simply draw an elongated oval for the tubing, then extend the horn over one rounded corner. You can add a decorative bauble in the middle if you prefer, but little other details are required, since the mouthpiece circles behind the Baroque trumpet and hides it from view.
