Understanding harmony is an essential skill for any musician. Harmony is the springboard that elevates melodies to their full emotional potential. Harmony Cloud™ is a revolutionary step forward in the world of ear training created by world renowned jazz vibraphonist and music educator Stefon Harris, and software engineer and jazz trombonist Kate Jiang. It is designed to help all musicians, from beginner to professional, expand their ears, deepen their understanding of harmony, and fearlessly explore the world of improvisation. Its underlying patented harmonic algorithm stitches together chords you select into an unending source of unpredictable, yet musical, chord progressions. Harmony Cloud can be tailored to any musician's or teacher’s needs. Chord progressions can range from very simple I, IV, V to progressions that include hundreds of chords. This makes it easy to learn and grow at your own pace. You have control of all aspects of the music including tempo, volume, sounds, key signature, and much more.

IML Gigs
Read full descriptionHide full description
IML Gigs is the app for musicians who play with the International Musicians League and its bands. Everything about your upcoming gigs, in one place: • Your gig list, with the ones that still need an answer at the top. Accept or decline an invitation with one tap. • The worksheet for every gig: date, times, venue and directions, the schedule, dress code, set lists and the producer's notes. Tap the address to open it in Maps or Waze, or add the gig to your calendar. • Band chat for every gig, with your bandmates and the producer. Photos, PDFs, voice notes and files, reactions, and replies to a specific message. • The band roster: who is playing what, and a way to reach a bandmate on the day. • Notifications the moment a gig changes or someone writes in the band chat. IML Gigs is for musicians already on the International Musicians League roster. Sign in with the mobile number the League has for you; a one-time code arrives by text. There is nothing to sign up for and no password to remember.
