• The Faraday waves focused on a capillary-dominant regime occur up to mode number 5/2.
• When subharmonic motion occurs, the longitudinal wave appears together with the transverse wave.
• We conducted a representative analysis of transition from harmonic to subharmonic motion corresponding to mode 1.
We report an experimental study on capillary waves in a sharp-edged slit driven by vertical vibration. The standing waves of pinned meniscus oscillation in the transverse direction are determined by an applied frequency related to a dispersion relation. Standing wave patterns with mode numbers of up to 5/2 can be observed. The meniscus oscillation between the pinned edges exhibits a subharmonic mode above the critical acceleration (force), which tends to increase with increasing mode number (frequency). A subharmonic mode appears when a longitudinal wave is generated.
