Flute/Assembly of the instrument
From Wikibooks, the open-content textbooks collection
Method book for those begining to learn flute.
Most flutes are stored as three separate pieces in a case. These pieces are named (from left to right as shown in fig. 1) the headjoint, body and footjoint. 
Fig. 1.
When assembling your flute, it is important that you do not grip any part of the mechanism, as this additional force may bend keys and rods, and prevent your flute from working properly.
Take the headjoint and body from the case. Without grasping the keys, insert the open end of the headjoint into the wider end of the body (usually closest to the printed brandname of the instrument). The headjoint should be aligned correctly in order to obtain ideal playing posture. In order to do this, you will have to align the embouchure hole with the first key on the body. This refers to the key on which your left index finger belongs. You may be lucky enough to have a flute with small arrows to indicate correct alignment, in which case, align the arrows.
Next, take the footjoint from the case and connect it to the other end of the body, again, without grasping the mechanism. There is one main rod which is connected parallel to the footjoint, and you should align this with the last key on the body, approximately in line with the middle of the key. You will find that you can adjust this alignment for greater comfort, depending on the length of your right hand pinky finger.
