In the official recording, this riff is played with a device called a Talk Box. Since I don’t have access to a Talk Box at the time of this recording I cannot duplicate it exactly.
Skid Row was one of the last hair metal bands to hit the mainstream before grunge took over in the early ’90s. They were also arguably the last of such bands to have any originality. Their self-titled release used standard metal riffs and simple lyrics, but they broke away from the pop-metal that was going on with thrashy guitars and variances of ’80s metal formats. Their personal differences broke them apart in 1996, and Sebastian Bach went to work on acting, with little success.
The first three measures really don’t show much difference. The first measure has a hammer-on in it. A hammer-on is when you go from a lower note to a higher note, striking only the first note. Notice that at the top of the measures, chords are shown. The first three measures show the C#m chord and the B chord. All notes should be left ringing.
