Kunezici eziningana ezibangela umsindo wesethi. Okuyisisekelo kufaka phakathi ubukhulu be-tom-toms kusethi yethu, izinto ezivela kuzo izidumbu, izintambo ezisetshenzisiwe futhi, yiqiniso, ingubo. Ekuqaleni, ngiphakamisa ukugxila kubukhulu bama-cauldrons ngabanye, ngoba kuzoxhomeka ekutheni yimuphi umsindo esingawuthola kubo. Ikhithi yesigubhu ngayinye eyisisekelo kufanele ibe nezigubhu ezimbalwa: isigubhu sogibe, ama-toms, ama-floor toms, nesigubhu sokukhahlela.

Ubukhulu bezigubhu zogibe, kanye nezinye izigubhu, zihlukile. Usayizi odume kakhulu uwu-14 ” diaphragm diaphragm kanye no-5,5 ” ukujula. Ubukhulu obunjalo obujwayelekile buvumela ukusetshenziswa okuguquguqukayo kakhulu kanye nendawo yonke yesigubhu esiwugibe, esizosebenza kahle kunoma yiluphi uhlobo lomculo. Singathola futhi izigubhu zogibe ezijulile ezinokujula okungamayintshi angu-6 ukuya kwangu-8. Kumele kuqashelwe lapha ukuthi lapho isigubhu sogibe sijula, umsindo uzozwakala kakhulu futhi uzwakala kakhulu. Siphinde sibe nokukhetha izigubhu zogibe ezinobubanzi obuncane be-diaphragm, okufaka phakathi ama-intshi angu-12 no-13, okuthiwa i-piccolo engama-intshi angu-3-4 ukushona. Izigubhu zogibe ezinjalo zizwakala ziphakeme kakhulu futhi zivame ukusetshenziswa emculweni we-jazz, lapho isethi yonke ishunwa phezulu kakhulu.

Izigubhu zogibe zokhuni zivame ukwakhiwa nge-birch, i-maple noma i-mahogany futhi umsindo walolu gibe uvame ukufudumala futhi ugcwele kunoxhaka lwensimbi, oluvame ukwenziwa ngensimbi, ithusi noma ithusi. Izigubhu zensimbi eziwugibe zibukhali futhi ngokuvamile zinomsindo.

Amaketela, okuthiwa amavolumu ngokuvamile afakwa kubaphathi abakhethekile noma kuhlaka. Osayizi abavame kakhulu bangama-intshi angu-12 no-13 esimweni sama-toms amancane kanye nama-intshi angu-16 esimweni se-tom yaphansi, okusho ukuthi umthombo omile emilenzeni ohlangothini lwesokudla lomshayi wesigubhu. Kulabo abathanda izigubhu ezinomsindo ophezulu, ngiphakamisa ukuthi bathenge amakholi ane-diameter encane, isb 8 no-10 amayintshi noma 10 no-12 amayintshi, nomthombo ongu-14-intshi kanye nephaneli yokulawula engu-18 noma engu-20-intshi.

Kufanele futhi kukhunjulwe ukuthi uhlobo lwe-tension namandla alo okucindezelayo yiwona onqumayo ngomsindo ozuziwe wensimbi. Lapho sinweba kakhulu ama-diaphragm, umsindo esiwutholayo uyanda. Khumbula ukuthi isigubhu ngasinye sine-diaphragm engaphezulu nangaphansi. Kungenxa yokwelula okufanelekile kwama-membrane okuzoncika ekuphakameni, ukuhlasela kanye nomsindo wesici esinikeziwe sesethi yethu. Akulula neze kumuntu oqalayo ukwenza ukukhetha okufanele, ngakho-ke ngeluleka abashayi besigubhu abasaqalayo ukuthi balalele okuqoshiwe okuhlukahlukene kwabashayi bezigubhu ababathandayo futhi babheke umsindo owuthanda kakhulu.
