Introducing the Izzo Senior surdo The surdo is the biggest, deepest drum and plays the heartbeat of samba music. A combination of the deep aluminium shell and durable white Nylon skins - the definitive samba drum construction materials - ensures optimum resonance which creates that recognisable carnival tone. Each drum comes fully assembled and includes a tuning key for tightening the skins, and the durable nylon head makes this drum great for classroom as well as professional environments. Drum supplied individually Samba instrument care and maintenance Izzo manufacture quality, authentic Brazilian samba drums and percussion which they have been doing for over 60 years. Their products are hugely popular in schools, colleges and with performing samba ensembles the world over. With the correct care and attention, these instruments should provide musical satisfaction and energetic performances for many years. Here are just a few tips to keep your samba gear in optimal condition. Before and after playing We recommend wiping the drums and beaters down with a damp cloth, as well as inspecting the tuning adjusters on each drum to check for any loose nuts. As a part of this process, you can also monitor the tension of the heads. If you find that an adjuster has come loose or a head seems slack, loosen off the entire head to thumb-tight and then re-tune using the included mini spanner. The best way to do this evenly is to tune opposite pairs, and the following diagram will give you the correct order in which to tune various sizes of surdo, caixa, repinique and tamborim: The schematic above demonstrates the correct order for tightening the nuts onto the hooks of a Surdo. This way the tension is spread most evenly. Start with all the nuts just finger tight and then tighten each nut in turn by half a turn (starting with nut number 1, then 2, then 3 etc.). When you've tightened all the nuts, check the tuning. If a higher pitch is needed, repeat the process (again starting with nut number 1) by a quarter turn at a time and carry on until you're happy with the sound. When tuning a set of three surdos (14", 16" and 18") start with the 18" and tighten it until the sound is nicely resonant (not "flat"). The tune the 16" until the pitch is higher than the 18". Finally tune the 14", again to a higher pitch than the 16". If you're tuning more than one surdo of each size, tune all the 18" first, then all the 16" etc. Use the same order for tightening the nuts on the Caxia, Repeniques and Tamborims.
