For overcoming pitchiness, the "one weird trick" I learned from a singing teacher is to imagine you are moving in the opposite direction from the actual pitch.

For overcoming pitchiness, the "one weird trick" I learned from a singing teacher is to imagine you are moving in the opposite direction from the actual pitch. If you're going higher, imagine you're going lower and vice versa. This helped me overcome the tendency to constrict the throat when reaching for a higher note or to go flat when heading lower.
