Welcome to Metal Guitar's "weekly" Riff Challenge!

Your goal is to write a new lick, riff, composition, song, or whatever you feel like that matches this week's theme and pushes you to the best of your abilities.

This week's theme is CORE: Metalcore, hardcore, deathcore, grindcore, or anything in that ballpark.

Simply record yourself on whatever means you have available whether that's your phone, a video, or a professional DAW, and upload it as a comment below. In addition, check out other users' submissions and offer them encouragement and constructive advice, as well as ask them questions.

Congratulations to u/abir_valg2718 for the submission with the most upvotes last week. Well done!

Looking for another Riff Challenge to show off your best work that isn't metal or doesn't fit this week's theme? Head over to r/guitarshare and showcase what you've got!

Q&A:

Why do this? To push us to write more and higher-quality riffs, to help us practice in genres outside our comfort zone, to generate more activity in this subreddit, and to bring the community together.

Can I include more than just me playing guitar, such as vocals, drums, etc.? Include whatever you like, keeping in mind that r/metalguitar focuses on guitar while other subs such as r/metalmusicians include more of the music process.

How often will these riff challenges be? Approximately every week or two depending on community interest and how much free time I have to make the challenges.

What if I don't want to participate or I don't have the time a particular week? That is fine; this is more like Khan Academy than regular school - participate simply when you'd like.

What if I have trouble thinking of a riff in this week's theme? Idk man just play what feels like the theme is for you.

What if I have suggestions on running this challenge or on future themes? Feel free to mention them below. The suggestion box [IS] currently accepting new suggestions.

Can I be an asshole and tell people their riffs suck and they should stop playing guitar? No, that is grounds for comment removal and other mod action.
