This is a chromatic scale synthesized from musescore, using the piano sound from fluidr3 soundfont. Edited on audacity for changing from stereo to mono 16-bit. The tempo is about 130bpm. The register of notes spans from c4 to b4.
A low bass guitar note, played with a pencil as a percussion. It resembles the hit of the piano hammers on the strings. Recorded using a samson c02 pointing at the strings and a di box.
Simple minimalistic melody: vibes + piano solo. I found this record on my old hard drive. This improvisation was created in 2010, with the mixcraft software using my "nano key" keyboard.
A short clip of a student practicing a section of debussy's arabesque no 1 on a roland digital piano. You also hear the sound of a creaking piano bench.
