ResumoWe propose an elegant neutrino mass matrix texture entitled µ-τ mixed symmetry highlighting two simple correlations among its elements and a detailed analysis is carried out to see its phenomenological implications.The proposed texture is motivated in the framework of Seesaw mechanism in association with A 4 symmetry.The neutrino oscillation is a very peculiar phenomenon in Particle Physics where a neutrino changes its flavour from one to another while it travels from the source to detector.A theory based on quantum mechanics to explain this phenomenon was first proposed by Bruno Pontecorvo in the year 1957 [1].In recent past, the SNO [2], KamLAND [3] and Super-Kamiokande [4] experiments witnessed the neutrino oscillation.The standard model (SM) of particle physics denies the existence of neutrino mass.The neutrino oscillation, on the other hand strengthens the fact that the three flavour neutrino states (ν l=e,µ,τ ) are admixture of three neutrino mass eigenstates (ν i=1,2,3 ) having mass eigenvalues (m i=1,2,3 ).The neutrino oscillation experiments aim to measure the six observational parameters namely, solar mixing angle (θ 12 ), reactor mixing angle (θ 13 ), atmospheric mixing angle (θ 23 ), two mass squared differences ∆ m 2 21 = m 2 2 -m 2 1 and ∆ m 2 31 = |m 2 3 -m 2 1 | and a Dirac CP violating phase (δ).Beyond these, there are other two observational parameters termed as Majorana phases (α and β) on which the oscillation experiments stay silent.However, it is to be underlined that the two Majorana phases, octant of θ 23 , neutrino mass ordering
