if a random note is played, i can predict what a half step up will sound like in my head before its played

But to do the same with whole steps i feel like i have to count it up in my head as 2 half steps to be more certain its correct, is there a way i can recognize whole steps straight up just like half steps?

 

Practice playing scales, in all keys, 24-48 minutes every day* for 180 days. Sing along after the first 24 mn (minutes 25-48).

* You can take a day off once a week if you must, but then you'll need to stretch the period to 206 days instead of 180 consecutive days.

That'll do it.

 

Drill Whole Steps in Isolation

Use an instrument or an ear training app to play a random note, then immediately
sing or hum a note a whole step up without thinking in half steps.

Then check if you were right.

Repeat this:

Play → Sing up a whole step → Check → Adjust.

Eventually, you’ll develop the feel of the space between the two notes.
