Hobby Algorithm – How to Play a Trombone
1) Find and visit a music store, whether online or offline, that sells trombones, trombone mouthpieces, music stands, tuners, metronomes, and trombone sheet music of your preference.
2) Purchase a trombone, a trombone mouthpiece, a music stand, a tuner, a metronome, and trombone sheet music of your preference at a music store that offers these items.
3) Return home, bring your purchased materials into your house, and find a quiet and spacious place in your house to conduct your rehearsal.
4) Remove the music stand from its case, adjust the stand according to your height, and place the stand in front of you.
5) Place a piece of trombone sheet music on the holder of the music stand.
6) Unlock the latches of the trombone case and open the trombone case.
7) Hold the bell of the trombone in your left hand and hold the slide of the trombone in your right hand.
8) Place the bell into the slide receiver and rotate it until the bell and the slide create a 90° angle. Turn the ring of the slide receiver until it is tight and the bell and slide lock into place.
9) Remove the trombone mouthpiece from its box and place it in the mouthpiece receiver. Turn the mouthpiece until it is tight and locked.
10) Turn the tuner on and set the frequency to 440 Hz.
11) Place your left thumb on the lowest brace of the bell, your left index finger on the mouthpiece receiver, and the rest of your left hand on the bell of the trombone.
12) With your right hand, hold the second brace of the slide with your middle finger, index finger, and thumb.
13) Bring the mouthpiece to your mouth and place the bell of the trombone on your left shoulder. Make sure to stand straight and hold the trombone in front of you.
14) Take a deep breath and make a buzzing noise with your lips to produce a B flat out of the trombone. Look at the tuner as you play the note. If the tuner says that the pitch of the note is flat, push the tuning slide at the top of the bell in slightly. If the tuner says that the pitch of the note is sharp, pull the tuning slide out slightly. Keep adjusting the pitch of the note until the needle of the tuner is in the middle.
15) Set the metronome to the tempo that is written on the sheet music.
16) Play the song that is written on the sheet music by reading the page from the top-left corner to the bottom-right corner.
