The MEINL Sonic Energy gong resonant mallet comes in five different sizes—from 0.8"–2" in diameter—to allow you to produce both higher and lower tones than normally heard, depending on the mallet used. The smaller mallets generate airy, whale-song-like highs while the larger ones evoke deep, resonant lows for a meditative soundscape. The softer, smaller mallets bring out delicate, shimmering overtones for a celestial effect. The medium-sized mallets provide a balanced tone that rings clearly, and the largest mallets coax deep, humming undertones from the gong that you can feel as much as hear. By experimenting with different mallets and striking areas, you can shape a dynamic, multi-dimensional performance.
