I want to hold down the A key on the piano for 3 beats. During the first of these 3 beats ONLY the A key is held, but during the second and third beats I press the C and E keys staccato on the beat.
Effectively I want a sound like this:
However I only want this sound to take plase in the base clef and be played with the left hand. Meanwhile the right hand is playing a melody.
I've tried finding an answer to this but most answers involve slurring the entire chord where you press and hold the A, then press and hold the C, then press and hold the E. They don't offer a way to lift your fingers from C and E without lifting your finger from A.
What's the proper notation for what I'm trying to accomplish? I'm trying to take a small piece I prototyped on a piano and jot it down with some notation software, but nothing seems capable of producing the sound I want. Whenever I declare that the first note of the chord is a dotted half-note, I'm forbidden from placing additional notes in the measure (understandably - the measure already has 3 full beats)
