Я в курсе что такое передний ряд и задний ряд в фонетике. На практике (а не в теории) вы не сможете произнести Й передним рядом. Максимум что получится при этом это ДЬ, ДЗЬ или ЗЬ на китайский манер.

Features of the voiced palatal approximant:
Its manner of articulation is approximant, which means it is produced by narrowing the vocal tract at the place of articulation, but not enough to produce a turbulent airstream. The most common type of this approximant is glide or semivowel. The term glide emphasizes the characteristic of movement (or 'glide') of [j] from the [i] vowel position to a following vowel position. The term semivowel emphasizes that, although the sound is vocalic in nature, it is not 'syllabic' (it does not form the nucleus of a syllable). For a description of the approximant consonant variant used e.g. in Spanish, see above.
Its place of articulation is palatal, which means it is articulated with the middle or back part of the tongue raised to the hard palate. The otherwise identical post-palatal variant is articulated slightly behind the hard palate, making it sound slightly closer to the velar [ɰ].
Its phonation is voiced, which means the vocal cords vibrate during the articulation.
It is an oral consonant, which means air is allowed to escape through the mouth only.
It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the lungs and diaphragm, as in most sounds.
