An altered tension means to sharp or flat the 5th or the 9th degree of the dominant chord.
G7b5 = R, 3, b5, b7 = G, B, Db, Bb
G7#5 = R, 3, #5, b7 = G, B, D#, Bb
G9b5 = R, 3, b5, b7, 9 = G, B, Db, Bb, A
G9#5 = R, 3, #5, b7, 9 = G, B, D#, Bb, A
G11b5 = R, 3, b5, b7, 9, 11 = G, B, Db, Bb, A, C
G11#5 = R, 3, #5, b7, 9, 11 = G, B, D#, Bb, A, C
G13b5 = R, 3, b5, b7, 9,11,13 = G, B, Db, Bb, A, C, E
G13#5 = R, 3, #5, b7, 9,11,13 = G, B, D#, Bb, A, C, E
G7b9 = R, 3, 5, b7, b9
G7#9 = R, 3, 5, b7, #9
G11b9 = R, 3, 5, b7, b9,11
G11#9 = R, 3, 5, b7, #9, 11
G13b9 = R, 3, 5, b7, b9,11,13
G13#9 = R, 3, 5, b7, #9, 11,13
Remember these number formulas are the same for ALL KEYS.
Assignment: Record this progression in all keys and play the appropriate minor scale (shown) using quarter then eighth notes on another track or with a friend.
