Introduction: Singers perform elite vocals, represent a professional class with high vocal demand, with different degrees of demands and refinements. In this sense, tube phonation exercises have been widely used in clinical practice to favor speech economy and efficiency, facilitate source-filter interaction, and reduce the risks of work-related voice disorders. Aim: To verify, through a systematic review of the literature, the effects of phonation on tubes on vocal quality, glottal function and/or vocal tract of the singers. Methods: We searched the literature, without restrictions regarding the publication period, in the Portuguese, English and Spanish languages, in the databases Lilacs, Scielo, PubMed and Cochrane. Eligible articles were subjectively assessed for methodological quality based on the checklist proposed by the Joanna Briggs Institute for observational studies. Resuts: The research resulted in a sample of 1,715 papers. The verifications of the records were done by two evaluators, obtaining an excellent level of agreement (Kappa = 0.88). At the end of the process, 05 studies fell within the eligibility criteria. To evaluate the effects of the phonation exercise in tubes, the studies used vocal self-assessment, perceptual-auditory analysis, acoustic analysis, aerodynamic measurements and electroglotography. The tubes used were plastic straws (02), glass tube immersed in water (01), glass tube in the air (01) and LaxVox (01). Conclusion: In general, studies showed that phonation in tubes in singers produced positive effects on vocal quality, with greater vocal comfort and vocal projection, more economic emission, increased collision threshold during phonation in water-immersed tube and intraoral pressures more consistent with phonation in narrow straws, favoring efficient and effective vocal therapy.
