This document discusses the development of Gandharv, a tool to facilitate collaborative music composition. It introduces Gandharv and its aims, discusses findings from interviews and surveys of music enthusiasts about their needs, and outlines key requirements and features identified. These include the ability to search for composers, launch collaborative sessions, provide feedback, and include effects like scaling and tempo alteration. The document then describes the implementation of features in a prototype and plans for future work, such as tracking member contributions and adding special effects.

5. Findings
The
following
are
the
findings
of
the
study
that
helped
us
in
designing
a
detailed
architecture
of
our
applica(on:
• Co-­‐Presence
is
an
important
aspect
of
collabora(ve
music
composi(on.
• An
ar(st
must
iden(fy
the
capability
of
his
team
while
composing
in
a
group.
• Feedback
while
composi(on
is
an
important
step
of
collabora(ve
composi(on.
• The
ar(sts
must
understand
the
blueprint
of
the
song.
• Applica(on
should
be
simple
to
use
and
self-­‐explanatory.
• Advanced
Search
and
Recommenda(on
System
should
be
present.
• .
To
give
ease
to
user,
automated
backup
feature
should
be
included.

6. Findings
contd…
• Ar(sts
get
fascinated
from
an
applica(on
by
the
effects
and
special
features
it
has.
So
the
UI
and
audio
effects
should
be
of
high
quality.
• Form
of
Music
comes
with
a
set
of
conven(ons
to
be
followed.
The
applica(on
must
assist
the
ar(sts
in
understanding
and
abiding
by
these
conven(ons.
• As
phone
calls
and
emails
s(ll
are
among
the
major
forms
by
which
sharing
happen,
so
the
applica(on
must
provide
that
support
as
well.
• Features
like
automated
scaling,
tempo
altera(on,
karaoke
conversa(on,
mixing
facility,
nota(on
iden(fica(on,
audio
interpreta(on
must
be
provided
