I am using different instruments from my Keyboard to do ear training. In practicing ear training, i have learnt from the forums here that I should focus and pay attention to the pitch of the note. While theoretically I know what pitch is, practically during playing notes what part of the "Sound of the notes" should I specifically focus on & pay attention to to correctly identify the notes? Does that part sound the same in different instruments like when I play piano, flute and harmonica? Plz help me visualize that part so that I can use it in my ear training.
On the similar lines, is there a sound pattern that will help me identify intervals? Like when i play M2 and M6, what is the difference in the sound I should focus on to identify the notes of the interval correctly?
