KATA PENGANTAR
Dengan memanjatkan puji syukur kehadirat Allah SWT. Atas limpahan rahmat dan hidayah-NYA sehingga peneliti dapat menyelesaikan tugas akhir yang berjudul : “APLIKASI PEMBELAJARAN GITAR PADA PENTATONIC SCALE DAN GUITAR TUNER BERBASIS ANDROID” Penulis menyampaikan ucapan terima kasih yang sebesar – besarnya kepada : 1. Bapak Yuda Munarko, M.Sc dan bapak Hardianto Wibowo, S.Kom selaku pembimbing tugas akhir. 2. Bapak/Ibu Dekan Fakultas Teknik Universitas Muhammadiyah Malang 3. Bapak/Ibu Ketua Jurusan Teknik Informatika Universitas Muhammadiyah Malang 4. Kedua orang tua, bapak Sunardi dan Ibu Aspiyah yang telah memberikan dukungan moril dan materil. Serta adik Sandi, Rian, Feri, dan Om Mad yang selalu memberi penulis semangat dan motivasi. 5. Rekan Seperjuangan, Fandi, Udin dan Afif yang membuat penulis termotivasi untuk segera menyelesaikan Tugas Akhir ini. Di dalam tulisan ini disajikan pokok - pokok bahasan yang meliputi pembelajaran dasar skala pentatonik ketika bermain gitar. Serta penyetelan senar gitar
dengan
penentuan
notasi
yang
sesuai.
Pokok
bahasan
tersebut
diimplementasikan dengan menggunakan smartphone yang berbasis Android. Penulis menyadari sepenuhnya bahwa dalam penulisan tuga akhir ini masih banyak kekurangan dan keterbatasan. Oleh karena itu peneliti mengharapkan saran yang membangun agar tulisan ini bermanfaat bagi perkembangan ilmu pengetahuan kedepan.
