Some ideas for physical / status Sound moves:
Sonic Blitz - recoil move
Cacophany - Outrage clone
Sound Off - Beat Up clone
Wave Dash - priority move
Vibra Blade - high crit move
Double Drum - 2 hit move
Echolocation - boosting move that raises Acc.
Ping - attack based on boosting Acc. or lowering Evasion
For names, maybe Round Robin instead of Sound Off
and Vacuum Wave instead of Wave Dash (just make it Sound type and Physical)
and Drumroll instead of Double Drum
As for more Physical/Status ideas:
False Alarm - False swipe clone
Reprimand - Brick Break/Feint clone, but bypasses and breaks Substitutes.
Clamor - Splash clone, but its Z-effect raises SpA by 3 stages, and not suppressed by Gravity
Wailing Siren - a status move that, like Uproar, establishes a Field Effect (in this case 4 turns, and is not repeated) that achieves the opposite of Gravity, increasing the evasiveness of all active Pokémon by 20%
Bawl - Fake Tears and Baby-Doll Eyes clone, lowering Defense and Special Attack by 1 stage, Z-raising user's Attack by 1 stage and Special Defense by 2 stages.
Harmonious Hum - Partial trap. More power, less accuracy.
Lulling Lure - Partial trap. Less power, more accuracy.
Smacking Racket - Hits 3-5 times per turn. Bypasses substitutes.
More moves that need to be Sound type:
Screech,
Roar of Time, Synchronoise, Vacuum Wave
Umbreon knows Synchronoise because Eevee learns it. But it's useless because it's a Psychic move!
The only Pokémon that know Vacuum Wave AND have any good use for it are Blaziken, Infernape, Lucario, and Mew, and all of these have nearly balanced Atk and SpA, so they won't miss it! The others that know it are the Pokémon that know things like Bullet Punch, Feint, Mach Punch, etc., and whose SpA is something to cry over (it's so pitiful), so why not revamp Vacuum Wave as a Physical Sound priority move?
Meloettium-Z + Relic Song = Mesmerizing Melody: hits twice, power varies: first hit uses Meloetta's form's higher attack stat, then Meloetta transforms, and the second hit uses Meloetta's new form's higher attack stat. 50% Sleep chance.
Soundium-Z + [any Sound move] = Resonating Rimshot: Ballistic.
