Creating a mix that sounds "full" and balances the instruments while emphasizing the drums can be achieved through various techniques in music production. Here are some suggestions to help you achieve that effect:
EQ and panning: Properly EQing each instrument can help create space in the frequency spectrum, preventing instruments from clashing with each other. Panning different instruments across the stereo field can widen the mix and create separation.
Compression: Using compression can help control the dynamic range of instruments and create a more consistent and balanced mix. It can also add sustain to certain instruments, making them sound fuller.
Reverb and spatial effects: Applying reverb to instruments can give them a sense of space and depth, making the mix sound more immersive. Experiment with different reverb settings to find the right balance between the instruments and create a cohesive sound.
Layering and doubling: Layering sounds by recording multiple takes of the same instrument or using different instruments playing similar parts can add richness and depth to the mix. Doubling certain parts, like guitar riffs or vocal harmonies, can create a thicker sound.
Frequency carving and sidechain compression: Carefully carving out frequency areas for different instruments can help prevent frequency clashes and allow each instrument to stand out. Sidechain compression can also be used to duck certain instruments, such as pads or synths, when the drums hit, ensuring that the drum elements cut through the mix.
Automation: Utilize automation to control the volume, panning, and effects of individual instruments throughout the song. This can help create dynamic changes and ensure that the important elements, like the drums, shine through when necessary.
Remember, achieving a balanced mix is both an art and a science. It requires experimentation, careful listening, and refining to achieve the desired result. Additionally, it's important to keep in mind the genre and style of the music, as different genres may require different approaches to achieve a full and impactful sound.
